Digital input module UR20-16DI-N-PLC-INT (Order No. 1315400000)
The UR20-16DI-N-PLC-INT digital input module can de-
tect up to 16 binary control signals. The sensors are
connected via a standard PLC connection (20-pole).
The inputs are N-switching (sinking). A status LED is as-
signed to each channel in a separate block. The module elec-
tronics can supply the sensors with power from the 4-pole
feed-in plug (connector4) via the PLC connection. Vice versa
the module can be supplied via the PLC connection.
For the PLC connection, the following applies: a maximum
current of 2A (with a max. of 1A per contact) can be taken
from the +24V connections or fed through the 0V con-
nections. In the case of a total current greater than 2 A, the
common ground wire must be connected to the 4-pin feed-in
plug (connector 4).
