5.4.5 Digital inputs
Only devices with optional motherboard and B-Client HR30 ‘Door control’ software option.
4 digital inputs are available. The inputs can be used for a door opener key, access control or a
customized application.
Assignment of inputs E1 to E4 depends on the configuration.
The inputs can be controlled by a simple switch or a relay contact. The corresponding input is
connected to common ground. An open input is recognized as ‘high’ due to the internal pull-up
resistor. Ground potential equals ‘low’.
Level
High = + 4.5 V to + 30 V or open
Low = - 30 V to + 1.5 V
