Digital and analog inputs and outputs example connections

The Remote module and Signal module can be used to control and or monitor digital and analog inputs / outputs such as switches, resistive sensors, pressure sensors secondary batteries etc.

Important

  • The negative power cable (0 V return) of the system must be connected to the same battery negative as all input and output devices that are being controlled or monitored by that system.

  • Each load must have both a supply and return connection to the module.
