EM-HP Extension module
The EM-HP Extension module enables the control of up to 4 loads with a high
current consumption. The power supply for these loads is established over elec-
tromechanical relays with a switching capacity of 4 A each.
For the speed control of high-efficiency pumps, the Extension module is equipped
with 4 PWM outputs that can be converted to 0-10 V outputs.
