TRICONEX 3674 | Dual Digital Output Module

TRICONEX 3674 is a dual digital output module primarily used for safety instrumented systems.

· Working voltage: usually 24V DC, with a voltage range between 16-30V DC, and a maximum voltage of 36V DC.

· Output current: Each channel can output a maximum current of 2A, and the surge current can reach 10A for 10ms.

· Isolation feature: It has a point isolation of at least 1500V DC, which can effectively prevent electrical noise and transient interference.

· Diagnostic function: It can continuously diagnose each channel and circuit, monitor the on/off status and module status of each point in real time, and also has 

load/fuse on-site alarm function.

· Working mode: Adopting a 2/3 voting mechanism to ensure reliable operation in the event of a single fault, suitable for power-off trip control programs.

· Mechanical characteristics: Adopting a mechanical key control design to prevent incorrect installation, with hot swappable function, and the ability to replace faulty 

modules online.

###Purpose:

· In the field of oil and gas, key drilling and refining equipment can be controlled on drilling platforms and refineries to ensure the safety and efficiency of the 

production process; In pipeline systems, pipeline valves and pressure regulating equipment can be controlled to prevent leaks and optimize transportation efficiency.
