This plugin is design for use with the J4CS range of actuators and designed to control the angle the actuator opens/closes depending on an input signal. This is to suit J4CS20 to 85, please ask for other sizes.
The input signal can be either 0-20mA, 4-20mA, 0-10V, 2-10V, with the most popular being 4-20mA. This system can also be set to fail open. fail close or fail freeze on loss of signal, and can also be fitted in conjunction with a BSR battery backup to enable the valve to open or close fully on loss of power.
