The PC1 time module is a transceiver allowing execution of time-logic programs. The device is characterized by versatility, high accuracy of the measured time based on the crystal oscillator and the possibility of its precise and repeatable adjustment. The relay can be used to extend short control impulses, e.g. controlling the operation locks, electromagnetic jumpers, bistable control, etc. The relay is used in automation and control circuits and access control projects, with logical dependencies on the state of the controller, door opening sensor (reed switch), exit button, etc.
