LE4 – Local expansion Units

LE4
 
Depending on the PLC used, up to 6 LE4 local expansion modules can be simply plugged into the base unit, i.e. PS4 or EM4. In this way, the controllers can be expanded, locally as well as remotely, by additional digital or analog inputs/outputs, counters, and also network interfaces.
