Advanced solenoid control modules are available as a pick-and-hold driver, proportional driver, closed-loop solenoid process control, pick-and-drop, load on-off power cycling, dual proportional valve controller and serially controlled solenoid driver. Applications for these compact 3- by 3-in modules include solenoids, valves, actuators, dc motors, electromagnets, hydraulics, LEDs, power amplifiers for electro-pneumatic proportional valves and pressure and flow control valves. To fit an application precisely, multiple variations of each are available and include single and two device—low-side driver, single and two device—selectable low- and high-side driver, 50 or 80 Vdc, high-current, serially controlled and bi-directional load cycling.
