PLCs, Power Supplies & Others

This Yokogawa analog output module converts digital control signals into analog field commands. It provides 16 isolated output channels for high-density I/O configurations. Engineers can deploy this unit in Centum VP systems for final element control. Its robust design ensures consistent performance in continuous process environments. The module delivers accurate signals to valves, positioners, and other actuators.

Physical Dimensions and Rack Installation

The module measures 4.9 inches in height and 1.4 inches in width. Its sturdy metal housing weighs approximately 1.8 pounds for secure rack mounting. A 64-pin DIN connector establishes all field wiring and communication pathways. The unit slides into standard Centum VP I/O racks without special tools. This design enables rapid module exchange during scheduled maintenance activities.

Output Channel Specifications and Signal Ranges

The module offers 16 isolated analog output channels for versatile connectivity. Each channel delivers 4-20 mA current signals for process control devices. The unit also provides 0-10 VDC voltage outputs for various actuator types. An onboard jumper configures each channel for the desired output type independently. This flexibility accommodates mixed output requirements within a single module.

Resolution and Accuracy Performance

The module achieves 16-bit resolution for precise control signal generation. Its accuracy reaches ±0.1% of full scale under standard operating conditions. The unit completes output updates in 10 milliseconds per channel. An internal digital-to-analog converter ensures smooth and stable signal transitions. This precision supports tight process control loops effectively.

Communication Interface and Data Exchange

The module communicates via the ESB bus at 10 Mbps data transfer rates. This bus receives setpoint values from the field control unit seamlessly. The unit supports HART protocol on each output channel for digital communication. This capability enables remote configuration and diagnostic access to field devices. Engineers can monitor valve position and actuator health through this interface.

Power Supply Requirements and Thermal Management

The module draws 300 mA from the 5 VDC backplane supply for logic circuits. It also consumes 200 mA from the 24 VDC field supply for output excitation. Total power dissipation reaches approximately 8 watts under full load conditions. An integral aluminum heat sink dissipates thermal energy effectively. This passive cooling design eliminates moving parts and improves reliability.

Diagnostic Monitoring and Fault Detection

The front panel features 16 green LED indicators for real-time output status. Two additional LEDs display module health and bus communication activity. The module performs continuous self-diagnostics on all analog output channels. It detects open-wire conditions and short circuits promptly. These diagnostic functions reduce troubleshooting time and improve system availability.

Environmental Ratings and Compliance Standards

The module operates reliably from 0 to 55 degrees Celsius ambient temperature. Its conformal-coated PCB resists moisture and airborne contaminants effectively. The unit withstands 95% non-condensing humidity for versatile plant deployment. It carries CE and UL certifications for global industrial applications. These approvals simplify equipment certification for international projects.
