Field Loop Monitoring & Fault Diagnosis
Features:
- DO, 24 VDC, self-protected, 16 pts
- 16-Point Supervised Digital Output Module
- 24 VDC Opto-Isolated, Commoned, Supervised TMR type
Designed for the most critical control programs, Supervised Digital Output (SDO) modules meet the needs of systems whose outputs remain in a single state for extended periods of time (in some applications, for years). An SDO module receives output signals from the Main Processors on each of three channels.
Each set of three signals is then voted upon by a fully faulttolerant quadruplicated output switch whose elements are power transistors, so that one voted output signal is passed to the field termination.
The 3624 Invensys Triconex Digital Output Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Emergency Shutdown (ESD) System: Serves as the last line of defense, safely shutting off process valves in hazardous chemical infrastructure.
Fire and Gas (F&G) System: Quickly verifies detector inputs and initiates local mitigation procedures.
Steam Turbine and Compressor Control System: Controls speed limits and overspeed trip parameters for large rotating equipment.
Boiler Management System (BMS): Ensures safe ignition, operation, and fuel isolation of utility boiler units.
A key feature of the 3624 SDO module is its fault diagnosis capability, extending from the internal rack to physical field devices. It utilizes voltage and current loopback circuits and online diagnostics to verify output status without altering the output signal. It proactively monitors and flags the following field anomalies:
Loss of field power or blown system fuse;
Open circuit or load absence (e.g., broken wire leading to a valve actuator);
Field short circuit that could cause incorrect energization of safe loads.
