Carlo Gavazzi Open PCB module with 4 contact inputs and 4 PNP transistor outputs G21405520700

Direct interface to the I/O���s of elevator floor stations, lift-car signals and lift controls. The input pulses are prolonged to 0.5 s to ensure transfer of fast pushbutton activations. Due to the small size of the module it can be integrated into most pushbutton panels. Only 3-wires needed to connect any number of I/O-units (including the DC-supply for the output load). Installerfriendly mounting, operation and maintenance without requirements for any special tools or programming.
