Description
Product Overview
The AO 3481 Analog Output Module from Triconex delivers precision analog control for safety-critical industrial systems. Built for Tricon Systems, this 8-channel module supports both 4–20mA and 0–10V outputs, ensuring compatibility with a wide range of final control elements.
Engineers rely on the AO 3481 for its SIL3 certification and fault-tolerant architecture, which includes continuous diagnostics that monitor output health without disrupting signal transmission. Each channel features isolation to prevent fault propagation and supports configurable fail-safe states for enhanced system integrity.
The module integrates seamlessly with Triconex safety controllers and supports both single and redundant configurations. Its compact form factor optimizes cabinet space, while its rugged design ensures reliable performance in hazardous environments such as oil, gas, and chemical processing.
