YOKOGAWA S9129FA I/O Module | Analog Input, 8-Channel, 4-20mA, for Centum VP/CS 3000

YOKOGAWA S9129FA module specifications. Analog input I/O module, 8-channel, 4-20mA, for Centum VP and CS 3000 DCS systems.

Product Overview

The YOKOGAWA S9129FA is an analog input I/O module from the S9000 series, designed for use with YOKOGAWA Centum VP and Centum CS 3000 distributed control systems (DCS). It provides 8 isolated analog input channels for receiving 4-20mA current signals from field transmitters. The module mounts in an S9000 series I/O nest and communicates with the control processor via the V-net or ESB bus.

Technical Specifications

• **​ Built-in Signal Conditioning:​ Linearization, scaling, and filter functions available

• **​ Wide System Compatibility:​ Fully supported in Centum VP, CS 3000, and ProSafe-RS

Applications

• Analog signal acquisition in Centum VP and CS 3000 DCS systems

• Receiving 4-20mA signals from field transmitters

• Remote monitoring of process variables

• Redundant I/O configurations for high availability

• Safety instrumented systems (with ProSafe-RS)

Important Notes

1. This module requires an S9000 series I/O nest and a compatible communication interface unit for operation.

2. External 24V DC loop power is required for 2-wire transmitters; not provided by the module.

3. For redundant systems, two S9129FA modules can be configured as a redundant pair with appropriate software license.

4. Configuration is performed via the Centum VP/CS 3000 engineering environment.

5. The module does not include the terminal block; order appropriate terminal block model separately if required.
