PLCs, Power Supplies & Others

This Yokogawa analog input module captures field sensor signals for Centum VP control systems. It offers 16 isolated differential channels for high-density analog measurement applications. Engineers can rely on this unit for accurate data acquisition in continuous processes. Its rugged construction ensures stable operation in demanding industrial environments. The module simplifies integration through standardized mounting and connectivity interfaces.

Physical Dimensions and Rack Compatibility

The module measures 4.9 inches in height and 1.4 inches in width. Its metal housing weighs approximately 1.8 pounds for durable rack installation. A 64-pin DIN connector provides all field wiring and communication pathways. The unit fits seamlessly into standard Centum VP I/O racks. This compatibility allows straightforward upgrades and system expansions.

Input Channel Specifications and Signal Ranges

The module provides 16 differential input channels for versatile signal connectivity. Each channel accepts 4-20 mA current signals from transmitters and sensors. The unit also handles 0-10 VDC voltage inputs for various measurement devices. An onboard jumper configures each channel for the desired input type. This flexibility reduces the number of spare modules required.

Measurement Resolution and Conversion Accuracy

The module delivers 16-bit resolution for precise process variable measurements. Its accuracy reaches ±0.1% of full scale under standard operating conditions. The unit completes conversion in 50 milliseconds per channel typically. An integrated digital filter reduces noise from electrical interference effectively. This filtering ensures stable readings for critical control loops.

Communication Interface and Data Protocols

The module communicates via the ESB bus at 10 Mbps data transfer rates. This bus exchanges real-time process data with the field control unit. The unit supports HART protocol on each input channel for digital communication. This capability enables access to smart instrument diagnostics and configuration. Engineers can monitor device health without additional wiring.

Power Consumption and Thermal Characteristics

The module draws 300 mA from the 5 VDC backplane supply for internal logic. It also requires 200 mA from the 24 VDC field supply for loop power. Total power dissipation reaches approximately 8 watts under full load. The unit uses passive cooling through an integrated heat sink design. This approach eliminates moving parts and increases long-term reliability.

Diagnostic Indicators and Self-Monitoring

The front panel includes 16 green LEDs showing real-time channel status. Two additional LEDs indicate module health and bus communication activity. The module performs continuous self-diagnostics on all analog input circuits. It detects open-wire faults and out-of-range signals effectively. These diagnostics reduce troubleshooting time and improve system availability.

Environmental Ratings and Standards Compliance

The module operates reliably from 0 to 55 degrees Celsius ambient temperature. Its conformal-coated PCB resists moisture and dust accumulation. The unit withstands 95% non-condensing humidity for versatile factory deployment. It meets CE and UL safety standards for global industrial installations. This compliance facilitates equipment certification for international projects.
