TRICONEX 3625A digital output module

The TRICONEX 3625A is a digital output module and an integral part of the TRICONEX Safety Instrumented System (SIS). It is primarily used to convert logic signals from safety controllers into electrical signals required to drive final field actuators. Below is its comprehensive detailed information:

2. Product Features

Triple Modular Redundancy (TMR): Adopts a TMR architecture. Each output channel is driven in parallel by three independent circuits, and the final output is selected via voting logic. This eliminates single-point failures and improves system reliability and availability.
Quadruple Output Circuits: Each output point is equipped with quadruple output switches, further enhancing redundancy for critical signal paths.
Comprehensive Fault Detection and Diagnostics: Features advanced online diagnostic functions that real-time monitor the status of each output switch and field wiring. It detects faults such as open circuits, short circuits, and power loss, and reports them promptly.
Configurable Output Types: Supports configurable normally open (NO) or normally closed (NC) outputs with diagnostics, enabling flexible adaptation to different on-site application requirements.
High Output Driving Capacity: Each output point can provide a maximum driving current of 1.7A, allowing direct drive of various industry-standard actuators.
Hot-Swappable Capability: Supports on-line replacement—modules can be replaced without shutting down the system, reducing system downtime.
