YOKOGAWA S9185FA I/O Module | Analog Output, 8-Channel, 4-20mA, for Centum VP/CS 3000

YOKOGAWA S9185FA module specifications. Analog output I/O module, 8-channel, 4-20mA, isolated, for Centum VP and CS 3000 DCS systems.

Product Overview

The YOKOGAWA S9185FA is an analog output 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 output channels for transmitting 4-20mA current signals to final control elements such as control valves, positioners, and variable frequency drives. 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

Key Features

• 8 Isolated Analog Outputs:​ Each channel is individually isolated for signal integrity

• Standard 4-20mA Output:​ Direct interface to control valves, positioners, I/P converters, and drives

• High Accuracy:​ ±0.15% span for precise process control

• Per-Channel Diagnostics:​ Individual LED status indication for each output

• Short-Circuit Protection:​ Built-in protection against field wiring faults

• Hot-Swappable:​ Module can be replaced under power without interrupting system operation

• Redundant Communication Support:​ Compatible with V-net and ESB bus redundancy

• **​ Configurable Output Ranges:​ Standard 4-20mA with optional 0-20mA or 0-5V (with termination)

Applications

• Control signal output to pneumatic and electric control valves

• Speed control of variable frequency drives (VFD)

• Positioning of actuators and dampers

• Analog setpoint control of process equipment

• Redundant I/O configurations for high availability systems

• Safety instrumented system outputs (with ProSafe-RS)

Important Notes

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

2. External 24V DC loop power is required for 2-wire field devices; the module only provides the control signal.

3. For redundant systems, two S9185FA modules can be configured as a redundant pair.

4. Configuration is performed via the Centum VP/CS 3000 engineering environment (e.g., Yokogawa Integrated Engineering Environment).

5. The terminal block is not included with the module and must be ordered separately.

6. Outputs can withstand continuous short circuit to common without damage.
