GPIO Module

The GPIO module is the central interface between BlueNet PDUs and external devices.

Connection made simple

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.
