Technical Specifications Supply: 18–32 V DC; speed input: 1 channel, 10 Hz–12,000 Hz; 1× 4–20 mA output; 6 inputs / 4 outputs, 24 V DC; RS-485 Modbus RTU, 9600–115200 bps; 14-bit resolution; -40 °C to +70 °C; IP20.
Functional Features PID speed control; remote setpoint adjustment; soft start / load sharing; overspeed protection; fault diagnostics and event logging.
Application Scenarios Networked generator sets, SCADA-integrated pump/compressor control, remote monitoring engine systems, distributed generation.
Performance Parameters Speed regulation: ±0.4% FSO; communication update rate: ≥100 ms; transient response: < 250 ms.
Material Composition ABS housing; FR-4 PCB; 16-bit MCU; galvanically isolated Modbus transceiver.
Structural Characteristics Rack plug-in form factor; front power/comm/status LEDs; rear terminal block; front configuration port.
Working Principle Measures engine speed, executes PID control, outputs 4–20 mA to actuator; Modbus interface exposes setpoints, status and diagnostics to remote systems.
Installation Requirements Mount in rack; connect speed pickup, actuator and RS-485 wiring; set device address and baud rate.
Usage Notes Follow network cybersecurity practices; backup configuration via Modbus; perform periodic communication integrity checks.
