Functional Characteristics

• 8 Individually Isolated Channels: 2×4 groups with 1500 VAC isolation prevent cross‑talk and ground loops, supporting mixed‑voltage loads.
• 14‑Bit Resolution: 2.44 mV LSB enables precise control of valves, drives, and actuators in process control.
• Per‑Channel Scaling: Software‑configurable scaling converts raw digital data to -10 VDC to +10 VDC outputs, adapting to diverse field devices.
• Built‑in Diagnostics: Under/overrange, power loss, and uncalibrated module detection trigger alarms; LEDs speed troubleshooting.
• Field Recalibration: FLASH‑stored calibration data allows on‑site adjustment or factory reset without replacing the module.
• 2 Isolated Groups: 2×4 output groups let users power each group separately, isolating safety interlocks from standard control circuits.
• 10.25 V Overrange: Supports valve/actuator positioning beyond nominal -10 VDC to +10 VDC ranges.
• Compact & Lightweight: 230 g, DIN rail mounting fits dense control panels; hot swappable with Genius Field Control chassis.
• BIU Compatibility: 170 mA BIU current draw integrates seamlessly with Series 90‑30 backplane communication.
• Global Power Compatibility: 24 VDC ±10% field power works with standard industrial power supplies.

Application Scenarios

• Process Control: Chemical, oil/gas, water treatment; 8 channels output -10 VDC to +10 VDC to control valve positioners, 14‑bit resolution ensures precise flow/pressure regulation, 2 groups isolate safety and control loops.
• Machine Automation: Packaging, textile, printing machines; 10 ms update rate controls fast actuators, 2.44 mV LSB enables fine‑tuning of motor speed/torque via VFDs.
• HVAC & Building Automation: Chiller, boiler, air handler control; 8 channels drive 4‑20 mA current loops via voltage‑to‑current converters, diagnostics prevent unplanned downtime.
• Manufacturing Automation: Assembly lines, test stands; -10 VDC to +10 VDC output controls servo drives, 1500 VAC isolation protects PLC from motor electrical noise.
• Energy Management: Solar inverters, battery storage; 8 channels adjust inverter output voltage, 14‑bit resolution optimizes power conversion efficiency.
• Legacy System Retrofit: Upgrades Series 90‑30 PLCs with 8‑channel voltage output expansion; preserves existing -10 VDC to +10 VDC actuator infrastructure.
• Remote I/O Racks: Distributed process control; 24 VDC power and 230 g weight suit remote cabinets, BIU enables central data aggregation via backplane.
