Digital input module UR20-4DI-2W-230V-AC (Order-No. 1550070000)
The digital input module UR20-4DI-2W-230V-AC can detect
up to 4binary control signals. One sensor can be connected
to each connector using a 2-wire connection. Both L and N
connections of each input are bridged internally. The four
inputs are galvanic isolated, they can be supplied with input
voltages between 110VAC and 230VAC. Solely AC meas-
urements can be run.
A status LED is assigned to each channel.

WARNING
Possible danger to life!
All signal lines must be supplied from the
same power system.
ATTENTION
The module can be destroyed by too high frequen-
cies.
The input frequency may be 65Hz at maximum, the
switching frequency 15Hz at maximum.
ATTENTION
The module can be destroyed by too high input cur-
rents of the sinal lines.
The inputs must be ensured using a slow fuse max. 4A.
