T8461C Digital Output Module Description
Module Role

T8461C is a safety type digital output unit in the HIMA safety system, whose main task is to reliably execute instructions issued by the safety controller to on-site devices. It is a key module in the "execution layer" of the safety system.

It is directly related to whether the equipment can be promptly cut off or reset to a safe state in dangerous situations.

Overview of Working Principle

Security processors (such as T8110/T8151) complete logical judgments

Send the result to T8461C

T8461C drives on-site execution of component actions

If the system detects an exception, the module will force the output to enter a safe state

The entire process is designed with the core principle of 'failure is safety'.

main function

Drive on-site execution mechanism
Control solenoid valves, contactors, relays, shut-off devices, etc

Implement safety actions
Used for critical operations such as emergency parking, energy cut-off, equipment isolation, etc

Ensure output reliability
The output circuit has the ability to detect and diagnose, reducing the risk of misoperation
