Additional Details

• The 7400166 includes the following additional information based on its standard use and documentation:
• Function: Connects digital output modules to field devices like valves, solenoids, and actuators, ensuring reliable signal transmission for safety applications such as emergency shutdown (ESD), fire and gas detection, and burner management systems (BMS). Maintains TMR integrity for fault-tolerant operation.
• Mounting: Typically mounted in a control cabinet or panel near the Tricon chassis (e.g., 8110, 8400); connects to digital output modules via proprietary Triconex cables.
• Compatibility: Compatible with Tricon v9.6 and later systems; specifically designed for use with digital output modules like 2652-1 and 2652-5. Integrates with TriStation 1131 software for system diagnostics.
• Configuration: Features screw terminals for secure field wiring; no user programming required, as it serves as a passive interface for signal routing.
• Certifications: Meets IEC 61508 SIL3, UL, CE, and Factory Mutual (FM) standards for Class I, Division 2 hazardous locations; complies with IEC 61131 environmental and EMC requirements.
