Description

The Triconex AO 3481S2 Analog Output Module is a high-performance component designed for safety-critical industrial applications, particularly within Safety Instrumented Systems (SIS).

It converts digital signals from the controller into precise analog outputs to control field devices such as valve positioners and actuators.

Frequently Asked Questions About AO 3481S2

Q1: What is the primary function of the AO 3481S2 module?
A1: The AO 3481S2 module receives digital control signals from the SIS controller and converts them into continuous analog signals (current or voltage) to drive external devices like valves,

actuators, or controllers, thereby regulating physical processes within a plant.

Q2: What types of analog signals does the module support?
A2: The module supports current outputs ranging from 4–20 mA (controlled) and 0–22 mA (over-range). It also provides over-range protection up to 36 V DC continuous.

Q3: Is the AO 3481S2 module hot-swappable?
A3: Yes, the AO 3481S2 module supports online replacement, allowing it to be hot-swapped without shutting down the system.

Q4: What is the resolution and accuracy of the module's output?
A4: The module offers a 12-bit resolution with an output accuracy of less than 0.25% of the Full Scale Range (FSR) within the temperature range of 0°C to 70°C.
