6G Controls - Leading Supplier of New & Original PLC 、DCS Parts and Automation Controller
Product Overview
The ASR133-S00/SR3S0 is a resistance signal input module developed by Yokogawa Electric Corporation for use in its CENTUM CS and CENTUM VP Distributed Control Systems. The module is engineered to interface directly with RTD temperature sensors and potentiometers, converting resistance variations into high-resolution digital values for control, monitoring, and diagnostics within the DCS environment.
Designed for long-term stability and accuracy, this module is commonly deployed in applications where precise temperature measurement or mechanical position feedback is required. Its compact form factor and industrial-grade construction make it suitable for continuous operation in demanding plant conditions.
Core Functions
The ASR133-S00/SR3S0 accepts resistance-based input signals from supported RTD elements or potentiometers. Internal signal conditioning and A/D conversion ensure accurate representation of field measurements, which are then communicated to the Yokogawa control system through the system backplane. The module supports stable measurement performance even in environments subject to electrical noise and temperature fluctuations.

Application Scenarios
The ASR133-S00/SR3S0 is typically used in process industries where resistance-based sensing is preferred. Common applications include temperature monitoring in reactors, furnaces, and heat exchangers, as well as position feedback for valves, dampers, and mechanical actuators using potentiometers.
Engineering Considerations
Proper selection of RTD type and potentiometer resistance range is essential to ensure measurement accuracy. Shielded cabling and correct grounding practices are recommended to reduce electrical interference. This module is intended exclusively for resistance-based inputs and does not support voltage or current analog signals.
