Product Description

The CP461-53 is a high-reliability central processing unit designed for Yokogawa CENTUM VP Field Control Stations (FCS), including AFV30S and AFV40S models. It excels in executing complex control logic and managing real-time process data with high deterministic precision. Equipped with a 400 MHz 32-bit RISC processor and 128 MB of SDRAM, the CP461-53 delivers the computational performance required for advanced PID control, sequence management, and multi-loop operations.

Designed for long-term industrial stability, the module supports a dual-redundant (Duplex) configuration, allowing instantaneous failover. This ensures critical control loops remain active even during hardware maintenance or unexpected component failures. The ISA G3 conformal coating enhances the module’s reliability in environments with corrosive gases or harsh industrial conditions.

Technical Specifications

Application Scenarios

The CP461-53 is widely deployed in high-density control environments, such as offshore oil platforms, integrated chemical plants, and thermal power stations. It is especially suited for applications requiring a large number of I/O points and tightly synchronized control across multiple Field Control Units (FCU).

Frequently Asked Questions

Q: What is the difference between CP461-50 and CP461-53?
A: The CP461-53 includes ISA G3 conformal coating as a standard feature, making it suitable for corrosive environments (e.g., sulfur or chlorine). The CP461-50 may not include this protection by default.

Q: Can the CP461-53 be hot-swapped?
A: Yes. In a duplexed redundant system, a single CP461-53 can be replaced online without shutting down the controller or interrupting process control.

Q: Is this module compatible with Vnet/IP?
A: Yes. The CP461-53 is fully compatible with Vnet/IP networks, which serve as the high-speed control backbone for CENTUM VP systems.
