EHR
Voltage-controlled relay
With an EHR voltage-controlled relay, you can change a 0...10V control
into two ON/OFF digital outputs.The voltage, where the relay becomes
active, can be adjusted with the two potentiometers located inside the
case. EHR is used, for example, in EH-105 air handling unit controllers
to control the ON/OFF dampers and the magnetic valves in cooling
mode.
