COILS AND ELECTRONIC CONTROLS Proportional Valve Controller—PCB Only— GENERAL SPECIFICATIONS Weight: 25 g (0.88 oz.) Connections: Screw terminals for 16–30 AWG wire UL and cUL Listed: UL508 CSA C22.2 No. 14-M91 DESCRIPTION 4–20 mA Input A printed circuit board-style (PCB) control amplifier for HydraForce proportional valves. Remote mounting in a protected enclosure is required. This model is designed for circuits with long wire runs or where electrical interference is a problem. OPERATION This control module supplies a proportional valve solenoid with a proportional control signal. The input signal to this controller can be from a 4–20 mA source. FEATURES • Adjustments and connections clearly labeled. • LED indication of output power level, input level and power on/off. • One unit covers supply voltages from 9 to 32 VDC. • No internal fuses; circuit limits current electronically. • Short circuit proof and reverse polarity protected. • Can be disconnected from coil when powered. • Maximum current adjustment does not affect minimum current setting. • Current sensing circuit maintains output current regardless of changes in input voltage or coil resistance. • Filter eliminates electrical noise; Independent ramp adjustments. • Dither frequency and amplitude are adjustable for maximum valve performance. RATINGS Supply Voltage: 9–32 VDC (UL and cUL approval is for 9–28 VDC operation only) Coil rating must be matched with supply voltage: RCOIL ≤ (VSUPPLY – 1.5 V) / I-Max. Control Input Signal: 4–20 mA current signal (see connection diagram) Input Resistance: 33 Ohms Output Current: up to 2000 mA (see ordering info.) Minimum Current Range: 0–500 mA (adjustable) Maximum Current Range: 600–2000 mA (adjustable) Ramp Up and/or Down: 0.01–5.0 seconds (independently adjustable) Dither Frequency: 70–350 Hz (±10%) Dither Amplitude: 0–10% of maximum current (adjustable) Dither Waveform: Triangular Operating Conditions: –20° to 85°C; 0 to 85% relative humidity SCHEMATIC V PS + (9-32 VDC) – NOT USED POWER GND ACTIVE REVERSE POLARITY PROTECTION STEP-DOWN CONVERTER V PS TO 5.5 V +5 V STEP-UP DC/DC CONVERTER +12 V –12 V INPUT, OUTPUT AND POWER SUPPLY INDICATORS RAMP UP RAMP DOWN +5 V CURRENT LOOP TRANSMITTER NOT USED CURRENT IN (4-20 mA) ANALOG GND INDEPENDENT RAMP CONTROL FUNCTION DITHER FREQUENCY R D R DITHER DITHER GENERATOR I-MAX.
