The GPIO module is the central interface between BlueNet PDUs and external devices.
The GPIO (general purpose input output) module is the central interface between BlueNet BN3000 – BN7500 power distribution units (PDUs) and external devices (e.g. door or signal contacts). Furthermore, it enables a physical connection to be established with the building control system for issuing alarms in response to set threshold values, such as when the residual current is exceeded (RCM – residual current monitoring).
The GPIO module features four programmable inputs and four programmable outputs that are visualised in the BlueNet BN3000 – BN7500 software user interface.
The input contacts provide an auxiliary voltage of 7 V and can be assigned to signal sequences. The floating output contacts can be controlled automatically by signal sequences or manually via the software user interface. Bi-stable relays enable loads of up to 2 A / 230 V AC or 2 A / 30 V DC to be switched.
The connection is established at one of the two sensor ports of the BlueNet BN3000 – BN7500 PDUs. There is no need for an external voltage supply to operate the GPIO module.
