CR-M110DC4LG Pluggable interface relay 4c/o A1-A2=110VDC gold plated contacts

As an interface, interface relays connect the electronic control level, for example PLC, to the level of the sensors / actuators. They take on different functions: switching DC or AC voltage loads with different ohmic, inductive and capacitive components, switching in the voltage range from a few mV to 250 V, switching in the current range from a few mA to 12 A, amplifying weak control signals, electrical isolation of control and load circuits as well as signal multiplication. The CR-M series has 13 different voltage voltages with 2-4 switch switches. A built-in test button can be selected for manual activation and locking of the output switches as well as relay variants with or without a built-in LED. Two basic variants are offered: standard base and logical base. Plug-in function modules such as Polarity reversal / freewheel diode protection, RC elements or surge protection extend the application range of the plug-in miniature relays.
