1. Product Overview
Brand / Series / Product Positioning
-
Brand: Honeywell
-
Series: Safety Analog Output Modules
-
Positioning: The FC-TSAO-0220M is a dual-channel Safety Analog Output Module designed for critical industrial automation systems. It converts control system signals into 4–20 mA or 0–20 mA analog outputs for actuators, valves, and field devices in SIS (Safety Instrumented Systems).
It ensures safe performance in demanding environments by incorporating fault detection, diagnostics, and de-energize capability. Suitable for sectors such as oil & gas, chemical, power, pharmaceutical, and wastewater industries.
