Connection of the digital inputs and outputs (example)

Open

Relay outputs

Relay outputs (1 on GT7.2x00, 2 on GT7.3x00) for activation of external components such as electronic door openers. The function and timing of the relays are configurable. Use a freewheeling diode and observe the maximum permissible switching voltages and currents (see technical data). The supply output Vout 1 (24 V DC) can be used to supply the external components, provided that the technical data are complied with.

Optocoupler inputs

One potential free input is provided for status acquisition. The function and timing of the optocoupler are configurable. Voltage must be applied to activate the input, which can be taken from the GT7 or supplied by an external source. Observe the maximum permissible input voltages and currents (see technical data).
