Overview
The Triconex 3805H Analog Output Module is engineered to provide accurate and deterministic analog control signals in safety-critical environments. Each of its 8 channels is electrically isolated and independently configurable, supporting output ranges such as 4–20 mA for standard industrial actuators and control valves.
Moreover, the 3805H is fully compatible with Tricon and Trident safety systems, integrating seamlessly into Triple Modular Redundancy (TMR) architectures. It features built-in diagnostics, including open-circuit detection and loop integrity monitoring, ensuring continuous feedback on system health. For instance, in a chemical plant, the 3805H can precisely modulate valve positions based on control logic while simultaneously reporting signal integrity to the controller.
In addition, the module is hot-swappable, allowing maintenance without system shutdown. Its robust design and compliance with IEC 61508 make it suitable for SIL 3-certified safety instrumented functions (SIFs).
