YOKOGAWA SR20-AC22 I/O Module | Thermocouple Input, 8-Channel, for Stardom Controller

YOKOGAWA SR20-AC22 module specifications. Thermocouple input I/O module, 8 channels, for Stardom network-based controller, 24V DC.

Product Overview

The YOKOGAWA SR20-AC22 is a thermocouple input module for the Stardom network-based control system. It provides 8 input channels for directly connecting thermocouple sensors (TC) to measure temperature. The module conditions the low-level TC signals, provides cold junction compensation, and converts them to digital values for the controller. It mounts on a Stardom base unit and communicates via the high-speed backplane.

• Scalable I/O:​ Expands temperature measurement capacity of Stardom systems

• Plug-in Design:​ Easy installation on Stardom base unit

• LED Diagnostics:​ Per-channel status indication

• Robust Design:​ For industrial temperature measurement applications

• Direct System Integration:​ Part of the Stardom control architecture

Applications

• Multi-point temperature monitoring in Stardom control systems

• Direct connection of thermocouples in ovens, furnaces, and process heaters

• Environmental chamber and HVAC system monitoring

• Process industries requiring distributed temperature measurement

Important Notes

1. This module requires a compatible Stardom base unit (e.g., ANB10) and a Stardom controller.

2. The specific thermocouple type (K, J, etc.) is defined by the model suffix ("C22"); verify compatibility with sensors.

3. Configuration, including TC type selection and scaling, is performed via the Stardom engineering tool.

4. The module does not include a terminal block; wiring is to the base unit's terminals.

5. Ensure proper use of thermocouple extension wire of the correct type for accurate measurements.
