High Quality Brand New Original Triconex 4351B Analysis Input Module

Description:

Triconex 4351B is a digital output module that serves as a vital part of the Triconex Triple Modular Redundancy (TMR) Safety Instrumented System (SIS). It is specifically engineered for critical industrial fields, delivering stable and secure control capabilities. There are some discrepancies in partial parameter data from different distributors. 

The module relies on TMR architecture and employs a two-out-of-three voting mechanism, which guarantees that a single-point fault will not lead to system breakdown. It is mainly utilized to drive on-site equipment like relays and solenoid valves by providing digital output signals. With features such as online maintenance and strong anti-interference performance, it meets the strict safety and stability requirements of high-risk industries. It is widely applied in safety-critical systems such as emergency shutdown and equipment protection in industries like petroleum, chemical engineering, and electric power, and can seamlessly integrate with other control systems to realize unified scheduling and monitoring.

Key Parameters

FAQ

1.Q:What is the core positioning of the Triconex 4351B, and which systems is it compatible with?

A:The Triconex 4351B is a digital output module with Triple Modular Redundancy (TMR) architecture dedicated to Safety Instrumented Systems (SIS). It is fully compatible with Triconex series safety control systems such as Tricon, Tri-GP, and Tricon CX. Additionally, it can seamlessly integrate with mainstream industrial control systems (including Schneider EcoStruxure Foxboro DCS) via standard protocols, providing reliable digital output drives for critical on-site equipment.

2.Q:How many output channels does the Triconex 4351B have, and what types of on-site devices can it drive?

A:The module is equipped with 16 independent digital output channels, each supporting 24V DC output with a maximum current of 1A per channel. It can directly drive common industrial actuators such as low-power relays, solenoid valves, indicator lights, and contactors. It is widely used in safety interlocking scenarios like Emergency Shutdown (ESD) and equipment protection in the petroleum, chemical, and power industries.

3.Q: What safety certifications does the Triconex 4351B hold, and how does it ensure fault tolerance?

A:The Triconex 4351B complies with the SIL 3 safety integrity level and TÜV AK 6 certification standards. Based on its TMR architecture, it adopts two-out-of-three voting logic: three independent circuit units of the module perform identical control calculations simultaneously, and the system takes the majority-voted result as the final output. A single-point fault in any unit will not cause system failure, and the built-in real-time fault diagnosis function triggers an immediate alarm when an abnormality is detected, ensuring the safety of critical processes.

4.Q:What about the shipment?
A:We can arrange shipment by DHL, FedEx, UPS,with competitive price, of course, customers can also use their own freight forwarders.

5.Q:How about the terms of payment?
A:Generally through T/T, Paypal.
