Product Description
The ASR133-S00/SR3S0 is a high-density analog input module designed for the FIO (Field network I/O) architecture used in CENTUM VP and ProSafe-RS systems by Yokogawa Electric Corporation.
This module is specifically engineered for Resistance Temperature Detectors (RTD) and Potentiometer (POT) inputs, converting resistance changes into high-precision digital signals for process monitoring and control.
With 8 fully isolated input channels, the ASR133-S00/SR3S0 ensures excellent signal integrity by eliminating ground loops and minimizing cross-channel interference. It is ideal for high-accuracy temperature measurement and position feedback applications in mission-critical industrial environments.

Maintenance and Integration FAQ
Does this module require a specific terminal block?
Yes. The ASR133-S00/SR3S0 is typically paired with compatible FIO terminal blocks (pressure clamp or screw type) to ensure secure wiring for 3-wire or 4-wire RTD configurations.
Can RTD and Potentiometer inputs be mixed on the same module?
Yes, hardware supports both types. However, each channel must be individually configured within the Yokogawa engineering environment to apply proper linearization and scaling.
Is the “SR3S0” suffix significant?
Yes. The suffix defines the style code, compliance standards, and hardware revision level, ensuring compatibility with specific system versions and environmental certification requirements.
