Model/code: Mfg Date (manufacturing date, blank), MP/COM (such as 5101, etc.), DIA/IPI (such as 5301, etc.), DO/AO/RO (such as 5401, etc.), EXT (such as 2281, etc.) are different module/interface numbers

Certification and Environment: TRIDENT, FM certification, T4 temperature rating (surface temperature limit corresponding to safety), 

Ta = 70℃ (ambient temperature), indicating that it is suitable for industrial scenarios with potential explosion risks (such as petrochemicals), ensuring the safe operation of equipment

Performance characteristics

High reliability: It adopts a triple redundancy (TMR) design. Through redundant hardware and software design, the possibility of single point of failure is eliminated, meeting the SIL 3 safety integrity level requirements.

Strong anti-interference ability: Electrical isolation is provided between the input and the logic circuit to ensure the stability and security of the signal, featuring fast signal acquisition speed and high anti-interference ability.

The diagnostic function is complete: It is equipped with online diagnostic functions, including open circuit, short circuit and ground fault detection. There are status indicator lights on the module, which is convenient for fault elimination and diagnosis.

Flexible communication: Supports serial communication (such as RS-232/RS-485), Modbus, OPC and other protocols, and can flexibly interact with other devices for data exchange.

Application field

Oil and gas: Used for monitoring valves, switches and alarm signals.

Chemical industry: Provide safety monitoring data such as equipment operation status and interlock conditions.

Power industry: Used for monitoring the status of circuit breakers, protective relays and other equipment.

Rail transit: Monitor the positions of signal lights, turnouts and the status of other key equipment
