Technical description
The digital input module reads 24V AC/DC values from the field using the
differential inputs and transmits, depending on these values, binary control
signals to the higher ranking controls via the fieldbus coupler.The 4 channel
digital input module is designed for a 2 conductor connection. The input sig-
nals are processed via the signal input connections E1 and E1 or E2 and E2,
E3 and E3 or E4 and E4.
Warning
The module has no power contacts. For field supply to downstream I/O mod-
ules, use a supply module.
RC filters are series-connected for noise rejection and switch debouncing.
They are available with time constants of 20 ms.
The positions of the different I/O modules in the configured node/station are
selectable by the user. A block type configuration is not necessary.
These input module can operate with all buscouplers of the
WAGO-I/O-SYSTEM.
