Yokogawa S9260DE Terminal Board Module

Product Introduction

The Yokogawa S9260DE Terminal Board Module is a digital input/output module developed for use in Yokogawa’s CENTUM and CS-series distributed control systems. It provides seamless interfacing between controllers and field devices such as switches, sensors, alarms, and solenoid valves. With its compact size and high reliability, the S9260DE is a trusted component for discrete signal management in demanding industrial environments.

Product Parameters

Applications

The S9260DE module is primarily applied in process and factory automation systems where discrete signal handling is essential. It is used for:

• Acquiring field status from switches, sensors, and limit contacts.

• Driving actuators, solenoids, alarms, and indicator lights.

• Supporting automation in oil & gas, petrochemical, water treatment, power generation, and general manufacturing industries.
  Its compatibility with Yokogawa’s control platforms ensures seamless integration into both new and legacy systems.

Product Advantages

• Compact Size: Small footprint saves cabinet space and allows high-density installations.

• Reliable Isolation: Opto-coupler technology protects against noise and surges.

• Proven Compatibility: Works seamlessly with Yokogawa ESB/N-ESB bus and controller racks.

• Easy Maintenance: Modular design simplifies replacement and reduces downtime.

• Industrial Durability: Wide operating temperature and humidity range for harsh conditions.

• Standardized Interfaces: Uses common 24 V DC I/O signals widely adopted in industrial automation.

FAQ

1. Q: How many digital input and output channels does the S9260DE provide?
   A: It provides 16 digital inputs and 32 digital outputs.

2. Q: What type of communication bus is supported?
   A: The module connects through Yokogawa’s ESB / N-ESB bus.

3. Q: What isolation method is applied in this module?
   A: It uses opto-coupler isolation for signal separation.

4. Q: Can it directly drive solenoid valves?
   A: Yes, within rated limits, but external relays are recommended for heavy inductive loads.

5. Q: What are the environmental operating limits?
   A: –20 °C to +60 °C operating temperature, and up to 95% RH non-condensing.

6. Q: How is the module mounted?
   A: It mounts on Yokogawa racks or terminal boards with pressure clamp connectors.

7. Q: Does the module provide diagnostic functions?
   A: Yes, basic health and status diagnostics are available.

8. Q: What grounding practices should be followed?
   A: Use single-point grounding and shielded cables for long runs.

9. Q: How is redundancy implemented with this module?
   A: Redundancy is achieved at system or rack level rather than at individual I/O channel level.

10. Q: What tests are recommended during commissioning?
    A: Continuity checks, insulation tests, functional loop tests, and communication verification.
