This model series of pulse width modulated (PWM) solenoid driver modules is designed to be used for open loop motion, speed, torque and pressure control systems. Acceleration and deceleration rates are adjustable. The output is unipolar and will drive all solenoids that have current requirements up to 5 amps. The command signal can be obtained from either a potentiometer or an external voltage source. This industrial grade module is a true high performance current regulator. It incorporates current loop feedback to maintain the output signal to the coil within 1% of the setpoint as the load impedance, input voltage, and ambient temperature are varied over the specified operating range. Pulse width modulated switching provides high efficiency as the output current is varied from minimum to maximum. Each pulse width modulated solenoid driver module includes the controls required to set the acceleration and deceleration times as well as the minimum and maximum output for the coil current. The module contains a regulated 5 volt power supply that can be used to power an external command potentiometer. The driver also has the ability to follow a remote command voltage signal. The output current to the coil will vary from the minimum to the maximum as the input signal is adjusted from zero to the rated value. The module requires a positive 10 to 30 volt DC power supply for operation. The circuit board is solder masked. All external power and solenoid connections are made to a barrier type terminal block with #6-32 captive wire clamping plates. External command signals are made to .25 inch male tabs. All external connections are clearly marked on the board. The board can be mounted in the user's control enclosure on standoffs or located in plastic mounting track. Applications: Proportional solenoid valves, electric and magnetic particle brakes and clutches, small dc motors operating in the torque mode. With controlled acceleration and deceleration.
