Description
Product Specification: YOKOGAWA CP451-51 Analogue Input Module
The YOKOGAWA CP451-51 is a high-performance analogue input module designed for Yokogawa’s CENTUM series Distributed Control Systems (DCS). Optimized for industrial process control, the CP451-51 ensures precise signal acquisition and reliable data transmission in challenging environments.
1. Product Description
The YOKOGAWA CP451-51 is a compact, 8-channel module that converts analogue signals (e.g., 4–20mA, voltage) into digital data for DCS processing. Key features include:
- High Accuracy: ±0.05% full-scale error for precise measurements.
- Wide Input Range: Supports multiple signal types (current, voltage, thermocouples).
- Isolation: Galvanic isolation between channels and system ground.
- Hot-Swap Capability: Allows replacement without powering down the system.
- Diagnostic Functions: Real-time monitoring of module health and signal integrity.

6. Selection Recommendations
- Input Requirements: Match signal type (current/voltage/thermocouple) and channel count.
- Environment: Ensure temperature and humidity ratings align with the installation site.
- System Compatibility: Verify compatibility with CENTUM series DCS models (e.g., CENTUM VP).
7. Precautions
-
Installation: Use anti-static wrist straps to prevent ESD damage.
-
Wiring: Follow Yokogawa’s wiring diagrams for proper signal and power connections.
-
Calibration: Perform periodic calibration to maintain accuracy.
-
Firmware Updates: Keep firmware current for optimal performance.
