Driver Board for Bi−stable Rotary Solenoids


User−Specified Conduction Time

You can set the duration of energization from 1 to 511 milliseconds in 1ms steps for clockwise and counterclockwise rotation. The factory settings have T1 and T2 both set at 14 ms.

Easy Interface With Exterior Equipment

Since the input trigger circuit is insulated by a photocoupler, and since the solenoid power supply (V1 & V2) is independent of the circuit-board power supply, interfacing with exterior equipment is simple and easy.


The board is fully coated from front to back with acrylic coating.


Since we use CMOS integrated circuit technology in the logic and counter circuits, the driver board is energy−efficient. It can obtain a large noise margin, and takes a wide range of power supplies

How To Set Pulse Duration

By setting the ON-OFF switches on the 9-bit dip switches, you can set the duration of current supply according to the pattern shown in the table below.
Dipswitch SW1 controls clockwise rotation, and SW2 controls counterclockwise rotation.
