The LLPA05 interface can be activated either from the outputs (DOUT, open-drain outputs) of a BMB01 Remote I/O Unit or from isolated contacts from third-party LLPA equipment (“Diode OR”).

The LPPA0X (where X=Number of interfaces) comprises a maximum of five separate interfaces each with a dual-zone selection and is housed in a DIN-rail mountable enclosure suitable for use within a central equipment rack.
