【Other Features】 [Structure] ENCLOSURE CHARACTERISTICS • High channel density resulting from innovative circuit design using advanced surface mount components • Single or dual channel models • Plug-in screw terminal blocks to secure wires up to 2.5 mm2 • Configuration components are easily accessed by removing the side cover or via connector front panel [Line & Load Monitoring] SIL certified relays are used for critical loops where careful consideration should be given to Line and Load Monitoring. In a de-energize to safety application a wire/coil failure leads to a safety status. In an energize to safety application line failures leads to a dangerous status. In both cases failure detection is important, if not essential. Other diagnostics applications are monitoring the load status to prevent spurious trips or to verify the condition of the individual coil in a redundant coil SOV. In F&G system line diagnostics is a must and regulated by NFPA 72 code. 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 (coil). To perform line monitoring from field device to controller, a SIL relay with built-in diagnostic circuit is required. GM International relays will perform diagnostics of the load, wire, power supply and internal coils in all operating conditions, providing an independent alarm contact as well as transparently transferring the fault indication to compatible DO cards. GM INTERNATIONAL PATENTED DIAGNOSTICS FETATURES • Works in all load conditions: On/Off • Operates with OPEN/CLOSE Relay • Some units are software configurable • Suitable for NE/ND, AC/DC loads • Transparent fault indication to compatible system • Monitors: • Load supply voltage • Load current • Load resistance • Earth leakage • Internal relay coils [Universal Mounting units] The same device can be used in all applications to reduce spare inventory. • DIN-rail stand-alone devices • Standard and customized termination boards • Power bus using standard TS 35 DIN-rail *For more details, please download the PDF or feel free to contact us.

【Main Uses】 ■ When the control equipment system cannot meet the required power (voltage and current) ■ When multiple contacts are required ■ When a reversal of the controller's safety function is necessary *For more details, please download the PDF or feel free to contact us.
