This Yokogawa analog output module translates digital commands into precise analog signals. It provides 16 isolated output channels for high-density control applications. Engineers can integrate this unit into Centum VP systems for valve and actuator regulation. Its reliable design ensures consistent signal delivery in continuous processes. The module supports various output types through flexible configuration options.
Physical Dimensions and Rack Mounting
The module measures 4.9 inches in height and 1.4 inches in width. Its durable metal housing weighs approximately 1.8 pounds for stable rack installation. A 64-pin DIN connector establishes all field wiring and communication links. The unit fits seamlessly into standard Centum VP I/O racks. This compatibility enables straightforward system expansion and module replacement.
Output Channel Specifications and Signal Types
The module offers 16 isolated analog output channels for versatile connectivity. Each channel delivers 4-20 mA current signals to field 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. This flexibility accommodates mixed signal requirements within a single module.
Resolution and Accuracy Characteristics
The module achieves 16-bit resolution for high-precision output signal generation. Its accuracy reaches ±0.1% of full scale under normal operating conditions. The unit completes output updates in 10 milliseconds per channel. An internal D/A converter ensures smooth transitions between setpoint changes. This precision supports demanding process control applications effectively.
Communication Bus and HART Protocol
The module communicates via the ESB bus at 10 Mbps data rates. This bus receives setpoint values from the field control unit reliably. The unit supports HART protocol on every output channel for digital access. This capability enables remote configuration of smart positioners and valves. Engineers can perform diagnostics without additional wiring or tools.
Power Consumption and Thermal Performance
The module draws 300 mA from the 5 VDC backplane supply for logic operations. It also consumes 200 mA from the 24 VDC field supply for output excitation. Total power dissipation reaches approximately 8 watts under maximum load. An aluminum heat sink dissipates thermal energy through passive convection. This design eliminates moving parts and enhances long-term reliability.
Diagnostic Monitoring and Status Feedback
The front panel includes 16 green LED indicators for real-time output status. Two additional LEDs display module health and bus communication integrity. The module performs continuous self-diagnostics on all analog output circuits. It detects open-wire conditions and short circuits immediately. These diagnostic functions simplify troubleshooting and reduce system downtime significantly.
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 installations. These approvals streamline regulatory compliance for international projects.
