  • Every year explosions endanger people, systems and plants around the world.

    Several industrial environments are classified as hazardous areas: places where explosion risks exist, or may exist, due to the presence of combustible, flammable substances and potential sources of ignition. In addition, electronic systems used on process plants are always at risk from surges caused by power faults or nearby lighting strikes. These surges could also affect systems located in or connected to hazardous areas as well as those in safe areas. Electronic systems rely on high performance of electronic components that have to be designed considering aspects like faster operation, smaller dimensions and lower power consumption. These factors reduce the ability to dissipate any significant applied energy and increase the exposure to overvoltage and surge currents. So, a surge protection is needed to ensure safety and availability of a plant.

    Surge arresters fulfill explosion protection requirements, ensure coordination with terminal equipment and meet the requirements resulting from the operating parameters of measuring and control circuits. Equipment and/or systems in potentially explosive atmosphere or contributing to safety within these atmospheres require a surge arrester suitably tested and ATEX approved. Intrinsically safe surge protection devices, in intrinsically safe circuits, have to meet the same standards of design and construction as the intrinsically safe equipment.

    GM International D9000 Series provides surge protection for all kinds of applications in different industries such as oil & gas, petrochemical, steel, etc. avoiding signal interruption and protecting control room equipment. D9000 Series surge arresters are ATEX approved in accordance with 2014/34/EU directive and can be installed in potentially explosive atmospheres. Since all GM International surge arresters for intrinsically safe circuits are classified in the "Ex ia" category, they offer the highest level of safety.

    • Easy maintenance: Integrated knife disconnection technology for each channel
    • Quick wiring: Grounding path via contact to DIN rail
    • Reduced spare inventory: Surge protection for most I/O signals: AI, AO, DI, DO, nominal 24V DV, maximum 36V (both IS and NIS)
    • Increases discharge capacity and reduces response time: 2-stage protective circuit (diode, g-discharge tube)
    • Unlimited IS applications: Input from Zone 0 (Zone 20), installation in Zone 1 and 2
    • Fits in any SIL loop: SIL3 Certification
    • Protection level: up to 20KA
    • Local & remote faster maintenance reaction time: fault indication versions available
    • Simple testing and documentation, reduced downtime: hot swap plug module available
    • Safe disconnection and signaling in case of overload

  • G.M. International is a course promoter of the TÜV Rheinland Functional Safety Program for Safety Instrumented Systems (SIS) trainings.

    The course focuses on functional safety aspects for the process, oil & gas, and chemical industries according to IEC 61508 and IEC 61511.

    The main objective of FSE Course is to provide all engineers involved in safety instrumented systems with elementary and necessary knowledge about functional safety, based on the leading international functional safety standards IEC 61508 and IEC 61511. A second objective is to give anybody attending the course the opportunity to have his or her functional safety competency confirmed by the TÜV Rheinland upon successfully passing the exam. So, why should you attend?

    FSE Course IEC61511 ed2.0 released in February 2016, clearly indicates as a ‘Normative’ requirement that:

    • Anybody involved in safety lifecycle activities shall be competent to carry out the activities for which they are accountable.
    • A procedure shall be in place to manage competence of all those involved in the SIS life cycle.
    • A periodic assessments shall be carried out to document the competence of individuals against the activities they are performing and on change of an individual within a role.

    With this course, examination and certification you can prove to your customers, peers and management, your competency in the field of Functional Safety. Success in the final examination certifies your functional safety knowledge on your personal name, adding a great value to your professional career and image.

    The course provider is the worldwide renowned Functional Safety Expert, Tino Vande Capelle.

    Tino is a Senior FS Expert (TÜV Rheinland, ID#109/05) & Trainer for Safety Instrumented Systems (SIS) of the TÜV Rheinland Functional Safety Program as an accepted course provider. Capitalizing on his 30+ years of process safety sector experience, offers a unique and practical approach of the IEC 61508:2010 & IEC61511:2016 FS standards in the industry.

    This is just a part of GMI training offer. We organize FSE Courses, IEC61511 Edition updates, seminars at companies, etc. You can contact us for more information on GMI trainings at this email: training@gminternational.com

    You can also discover our Safety Academy!

    An innovative series of webinars presented by Tino Vande Capelle and dedicated to Functional Safety.

  • Safety of industrial processes is a fundamental aspect to guarantee an operational environment that is safe from threats. A secure plant allows the protection of heterogeneous company resources and allows savings on costs.

    An important worldwide gas company has chosen GM International as its reference brand to develop a comprehensive safety solution able to cover all present and future needs in coil controlling and monitoring.

    The challenge

    The company felt the need to adapt the safety loop in its plants, no longer adequate and that represented a disadvantage.

    The installations at the plants included just one solenoid valve connected to the DO card of Yokogawa (Prosafe RS – SD541) without any feature about the coil operation in case of malfunction, that means without a feedback if the coil was out/burned.

    Prevention of the contact chattering, spurious load activation/deactivation and premature damage of the relay unit is a critical success factor.

    The solution: product adopted

    Considering the specific customer requests, GMI offered the opportunity to test the D5096S, at the first stage, in order to know all the features offered by the device. Line monitoring is the solution provided to the customer to have a feedback in case something is wrong on the solenoid valve. With GMI D5096S it is possible to obtain information on the DO card (SD541), through its alarm the customer could be informed quickly of all the electrical malfunctions. Line monitoring pulses are generated by DO cards to verify the integrity of the line and load, in either energized or de-energized state.GMI D5096S safety relay was connected to the Yokogawa Prosafe RS (SDV541 DO card) and to the solenoid valve Asco Joucomatic (series 126) Eex d

    GMI D5096S is a relay module suitable for the switching of safety related circuits, up to SIL 3 level for high risk industries and are used in critical loops where careful consideration should be given to line and load monitoring. It provides isolation between input and output contacts. A wide compatibility towards different DCS/PLC is guaranteed: driving line pulse testing, executed by DCS/PLC, is permitted by a dedicated internal circuit, to prevent relay and LED flickering. D5096S has 2+2 SPST relay contacts connected in parallel and then in series to avoid spurious trip and to increase availability.

    Control system diagnostic capabilities are designed to work when no device is interposed between the control system and the load. If a relay is placed in the loop, the diagnostic function stops at the relay input circuit. To perform line monitoring from field device to controller, a SIL relay with built in diagnostic circuit is required.

    The results

    The adoption of GMI solutions has allowed to the company to structure a safety platform in line with the corporate plants’ safety strategy, and then thanks to GMI safety relay characteristics in terms of compact design, the gas customer was able to integrate it in its infrastructure efficiently, without any expensive add-on features. Another important advantage was represented by the power bus system that consists of standard DIN-Rail modules mounted on DIN-Rail Bus connectors. With GMI devices, it is always possible to remove modules, without disconnecting the bus connector which remains attached to the DIN Rail. Communication bus is provided, on suitable models, to transmit via Modbus to DCS PLC logic solver. Cumulative Fault Alarm indication is provided on the Bus connection.
