Functions of the expansion module: controlled dosing and alarms

This expansion module was developed and designed by daruifuno. It is mainly used with multi-parameter series controllers. It can reduce the weight of the controller itself and the complexity of wiring. The external expansion module supports 5 channels of 4-20mA current and 5 configurable relays by default. The function of the relay is mainly reflected in controlling dosing, alarms, cleaning, etc., or controlling other equipment based on measured values. Users can use it according to their own needs.
