• Weight: ~0.5 kg.
• LED Indicators: “FLD PWR” (external field power present); “OK” (backplane power, configuration, no hardware faults).
• Software Compatibility: VersaPro Software Version 2.0+; VersaMax Ethernet NIU Firmware Version 1.10+; VersaMax PLC CPU Firmware Version 2.10+.

Functional Characteristics

• 8-Channel Density: 8 single-ended channels maximize I/O coverage for cost-efficient voltage signal control.
• Software Range Selection: Bipolar/unipolar mode selected via software, no manual jumper changes.
• Output State Management: Software-configurable default/hold last state operation for error handling.
• Optical Isolation: 250 VAC continuous, 1500 VAC for 1 minute isolation protects logic circuits from field-side noise/surges.
• Onboard Diagnostics: Detects loss of field power, backplane power, and output driver faults, with LED status indication for quick troubleshooting.
• Fast Update Rate: 10 ms per module ensures real-time responsiveness to dynamic process changes.
• Backplane Power Efficiency: Low 50 mA draw from 5V backplane minimizes power load on the system.
• Seamless Integration: Works with VersaMax CPUs/NIUs, providing 8 words of analog output data for host interfaces.

Application Scenarios

• Process Control: Chemical plants, oil refineries, and water treatment facilities for valve positioning, pH adjustment, and flow control with voltage-driven actuators.
• Manufacturing Automation: Assembly lines and packaging machines connecting variable frequency drives (VFDs), positioners, and heaters to PLCs for closed-loop control.
• Building Automation: HVAC systems controlling dampers, valves, and VFDs with 0-10V or ±10V control signals.
• Energy Management: Power generation/distribution for generator voltage regulation, transformer tap changer control, and grid reactive power management via voltage outputs.
• Test & Measurement: Lab and production line testing requiring high-channel-count voltage signal generation with 13-bit precision.
• Remote SCADA: Unattended sites with VersaMax PLCs, leveraging external field power, isolation, and diagnostics for reliable long-term operation.
