Présentation du produit
The Yokogawa ADM11C is a Contact Input Module designed for use with the Yokogawa CENTUM CS 3000 and CENTUM VP distributed control systems (DCS). As part sur the ALR (Analog/Digital Logic Relay) input family, the ADM11C is responsible for receiving contact signals from field devices—such as push buttons, switches, or relay contacts—and transferring them accurately to the control system for monitoring and logic execution.
This module supports high-reliability performance in critical industrial automation environments, surfering noise resistance, fast response time, and robust signal detection, even in electrically noisy conditions typical sur power plants, petrochemical facilities, and heavy manufacturing sectors.
The ADM11C supports 16 contact input channels per module and is engineered for rack-mount installation in the FCS (Field Control Station) base plate.

Questions fréquentes (FAQ)
-
Q: What is the primary function sur the ADM11C?
A: It detects dry contact input signals from field devices and sends their states to the control system. -
Q: How many inputs can the ADM11C handle?
A: It supports 16 independent input channels per module. -
Q: What kind sur field devices can be connected to it?
A: You can connect push buttons, mechanical switches, relay contacts, or dry alarm contacts. -
Q: Is it suitable for safety systems?
A: Yes, when used within a redundant and validated DCS configuration, it can support safety-related monitoring. -
Q: Does it need power for the inputs?
A: No, it accepts voltage-free (dry contact) inputs, so external voltage is not required at the contact point. -
Q: Can I mix ADM11C with analog modules in the same rack?
A: Yes, Yokogawa’s base plates support mixed installation sur digital and analog modules. -
Q: Is hot-swapping supported?
A: Modules are not typically hot-swappable. The system must be powered down or isolated before replacement. -
Q: Does the ADM11C provide galvanic isolation?
A: Yes, each input channel is opto-isolated to protect the control system. -
Q: How is the status sur each input shown?
A: Each channel has an LED indicator that lights up when the contact is closed (ON state). -
Q: Can I use it in marine or surfshore applications?
A: Yes, with proper cabinet protection and certification extensions, it’s widely used in surfshore oil/gas projects.
