Further details:
As an interface, interface relays connect the electronic control level, such as PLCs, with the level of sensors/actuators. They perform various functions such as switching DC or AC loads with different resistive, 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, providing galvanic isolation between control and load circuits, and signal multiplication. The CR-M series offers 13 different coil voltages with 2-4 changeover contacts. An integrated test button for manual operation and locking of the output contacts, as well as relay variants with or without integrated LED, can be selected. Two base variants are offered: standard base and logical base. Pluggable functional modules such as reverse polarity protection, freewheeling diode, RC elements, or surge protection expand the application areas of the pluggable miniature relays.
