APPLICATION
The PD 621 has six general-purpose digital channels, which are normally all configured for either input or output. When configured as an input device, the BM 005 Base Module is used. When configured as an output device, BM 006 is used. Alternatively, by configuring channels 1-4 as inputs and channels 5 and 6 as outputs, the latter can use the two built in relays in BM 004. All of these combinations provide easy-to-use DIN-rail mounting.
