Pluggable universal relays CR-U

Pluggable interface relays are used for digital signals. They are used for electrical isolation, amplification and signal matching between the electronic controlling, e.g. PLC (programmable logic controller), PC or field bus systems and the sensor / actuator level. In contrast to electronic switching devices, pluggable interface relays don’t use additional internal protective circuits and thus are overload-proof against short-time variations like current or voltage peaks.
