Product Description
The CP461-50 S2 is a high-performance central processing unit for the Yokogawa CENTUM VP and CS 3000 Distributed Control Systems (DCS). It functions as the primary execution engine within Field Control Units (AFV30/AFV40) and supports dual-redundant “Pair & Spare” architecture, providing near-continuous availability.
The S2 hardware style is an optimized revision of the original CP461, featuring improved component reliability and enhanced thermal dissipation. It is designed for complex industrial processes, handling intensive PID control, sequence logic, and high-speed data acquisition via dual-redundant Vnet/IP networks.

-
Vnet/IP Integration: Provides high-speed communication with HIS and other FCS modules across the plant network.
Frequently Asked Questions
Q: Can I mix an S1 and S2 style module in a redundant pair?
A: No. Yokogawa recommends using two identical modules (both S2) for synchronized timing and firmware compatibility.
Q: Does the CP461-50 S2 support explosion-proof environments?
A: No. This model is Standard Type without explosion protection. For hazardous zones, use CP461-E suffix modules.
Q: What is the typical battery life for memory backup?
A: The S9450FE battery should be replaced every 3 years to ensure the 72-hour data retention remains reliable.
