Technical Specifications Supply: 18–32 V DC; speed input: 1 channel; 1× 4–20 mA output; 2 digital setpoint select inputs; 12-bit resolution; -40 °C to +70 °C; IP20.
Functional Features Dual preconfigured speed setpoints; digital select input; PID control; soft transition between setpoints.
Application Scenarios Dual-speed engines, idle/rated speed selection, two-speed pump/compressor drives.
Performance Parameters Setpoint repeatability: ±0.2% FSO; transition time: < 500 ms.
Material Composition ABS housing; FR-4 PCB; MCU; analog output stage.
Structural Characteristics Rack plug-in module; front status LEDs; rear terminal block.
Working Principle Selects between two preprogrammed speed setpoints via digital input, smoothly ramps speed to selected setpoint.
Installation Requirements Wire setpoint select switch; configure both speed setpoints; adjust ramp rate.
Usage Notes Set ramp rate to avoid engine stress; verify both setpoints during commissioning.
