TRICONEX 3805E

The TRICONEX 3805E module is a key component in the Triconex Safety Instrumentation System (SIS) of Invensys (now acquired by ABB). It is an analog output module, which is mainly used to convert the digital signal of the control system to analog signal, drive the actuator, and realize the control of the process. The module has the characteristics of high reliability, high precision and high safety, and is widely used in the safety instrument system of petrochemical industry, electric power industry and so on.

Main function

Analog output: Converts digital signals into 4-20mA analog signals to drive actuators (such as valves, motors, etc.).
Fail-safe: with fail-safe function, in the event of failure, the output signal will automatically enter the safe state.
Diagnosis function: Provides rich self-diagnosis functions to facilitate fault diagnosis and maintenance.
