Technical Specifications Supply: 24 V DC ±10%; 2 isolated channels; input: 4–20 mA per channel; output: 0–2 A continuous per channel; 12-bit resolution; dither: 20–400 Hz software-adjustable per channel; operating temp: -40 °C to +85 °C; IP40; DIN rail mount.
Functional Features Per-channel digital current control; independent dither tuning; short-circuit and open-load detection; Modbus RTU configuration & monitoring; fault logging.
Application Scenarios Dual-valve turbine governor systems, dual-actuator engine fuel control, multi-valve hydraulic servo loops, industrial valve control panels.
Performance Parameters Current accuracy: ±0.3% full scale; response time: < 12 ms; channel-to-channel isolation: 1000 V AC.
Material Composition Steel sheet housing; dual digital control circuits; power semiconductor output stages; insulated screw terminals.
Structural Characteristics Standard DIN rail mounting; front channel status LEDs; rear terminal block and Modbus communication port.
Working Principle Each channel independently executes closed-loop digital current regulation, delivering proportional output current to the connected solenoid valve; all parameters accessible via Modbus.
Installation Requirements Mount on 35 mm DIN rail; wire each valve circuit separately; connect RS-485 for configuration; calibrate zero and span per channel.
Usage Notes Route valve wiring separately to avoid crosstalk; calibrate each channel during commissioning; perform periodic fault diagnostics via Modbus.
