Description
Interface relays connect the electronic control level as an interface, e.g. PLC to the level of the sensors/actuators. They take on different functions: Switching of DC or AC voltage loads with different ohmic, inductive and capacitive components, switching in the voltage range from several mV to 250 V, switching in the current strength range from a few mA to 12 A, amplifying weak control signals, potential separation of control and load circuits as well as signal multiplication. The CR-M series has 13 different coil voltages with 2-4 changeover contacts. A built-in test button for manual operation and locking of the output contacts as well as relay versions with or without built-in LED can be selected. Two base variants are offered: Standard and logical sockets. Plug-in function modules such as reverse polarity protection / snubber diode, RC elements or overvoltage protection extend the application areas of pluggable miniature relays.
