DUAL VALVE - DUAL ADJUSTMENT VALVE DRIVER BOARD

DUAL VALVE - DUAL ADJUSTMENTVALVE DRIVER BOARDIn an effort to provide our distributor customerswho carry not only the Pulsar valve product line butalso any other proportional PWM valve products,OEM Controls has created the DUAL Valve –DUAL Adjust Valve Driver Board. The primarydesign goal of the DUAL Valve – DUAL AdjustPCB was to produce a PWM board that could beeasily converted by our customers from their dualcoil Proportional Duty Cycle (PDC) applications totheir Proportional Current (PC) applications. It hasboth types of outputs running simultaneously.Large, wire jumpers with silkscreen identificationlettering allow the customer to configure the boardto operate either the Parker Pulsar (Apitech – 33 or63Hz) PDC valve or most diode clamped PWMvalves.This allows the customer to inventory one PCB formost dual coil applications.Technical SpecificationsPower SupplyCommand Input9V - 32VEither Potentiometer (10kΩ non-CT) or Voltage (0.5V to 4.5V)Max Output Current PWM : 4 Amps each; PDC : 3 Amps eachFrequency (hardwareconfigured)Current RegulationTrimpot AdjustmentsPWM : 33 HZ - 250 Hz; PDC : 33 Hz or 63 Hz - jumper selectable(75Hz standard also available)≤ 5% errorIndividual adjustments of A & B directions for Threshold, Hi Range (Maxout), and LoRange. Ramp adjustments are made with 1 trimpot for both directions.Auxiliary Output (X)The Aux output is active when the power switch is closed. It outputs raw Vbat minusone diode drop (about 0.5V).LED Illuminated when pcb is active also used for assisted potentiometer centeringMountingDirect : EMS4, EJS3, RS; Remote for all other controllersProtection Reversed power supply, Output blocking diode, Short circuit, ThermalEnvironmental Operating temperature = -40C to +70CFull Moisture protection = silicone based conformal coatingEMC protection = CE ratingNote: This board was not designed to include single coil or flow control electro-hydraulic valves. Such valves require boardsconfigured specifically for the application.02/06
