The Master Module interfaces Dupline to any Elevator Controller with a RS232 or RS485 port.
Direct interface to the I/Os of elevator floor stations, lift-car signals and lift controls. The input pulses are prolonged to 0.5 s to ensure transfer of fast push button activations. Due to the small size of the module it can be integrated into most push button panels. Only 3-wires needed to connect any number of I/O-units (including the DC-supply for the output load). Installer friendly mounting, operation and maintenance without requirements for any special tools or programming.
