AO 3481S2 Triconex Analog Output Module
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.
