The Yokogawa ADM52C-2 is a Contact Output Module specifically engineered for use in distributed control systems (DCS), particularly within the CENTUM CS3000 or VP series architectures. Designed with high reliability and robust output performance, this module serves the purpose of converting digital signals into contact outputs, which are then used to drive external actuators such as relays, alarms, or solenoid valves.

The ADM52C-2 is favored for its stable signal integrity, isolation from field wiring, and long service life. This makes it ideal for mission-critical industrial control applications where contact-type outputs are required for safe equipment operation or for driving fail-safe systems. Its seamless integration into Yokogawa’s rack-based I/O systems ensures minimal engineering effort and consistent performance across the control environment.

FAQ

1. What type of output does the ADM52C-2 provide?

   The module provides dry contact (mechanical relay) outputs that can drive external devices directly.

2. How many channels are available in the module?

   The ADM52C-2 features 16 independent output channels.

3. Is the module hot-swappable?

   No, for safety and proper system operation, power must be shut down before replacing the module.

4. Can this module drive both AC and DC loads?

   Yes, each contact is rated for 2 A at 250 VAC or 30 VDC for resistive loads.

5. Is ADM52C-2 compatible with CENTUM VP?

   Yes, it is fully compatible with Yokogawa’s CENTUM VP and CS3000 systems.

6. Does the module have status indicators?

   Yes, each channel is equipped with an LED indicator to show output status.

7. What is the insulation method used?

   Relay isolation is used between control logic and output terminals for enhanced safety.

8. Can the module detect its own faults?

   Yes, the ADM52C-2 includes built-in diagnostics for module-level faults.

9. Is there a limit to switching frequency?

   Yes, due to mechanical relay operation, high-frequency switching is not recommended; ideal for low-cycling applications.
