AnalogueinputmoduleUR20-8AI-I-PLC-INT(OrderNo.1315670000)
The analogue input module UR20-8AI-I-PLC-INT can detect
up to 8analogue sensors with 0 ... 20mA or 4 ... 20mA. The
resolution is 16bit per channel. The sensors are connected
via a standard PLC connection (20-pole). The measurement
range is dened using parameterisation. 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 (connector4) via the PLC connection. Vice versa
the module can be supplied via the PLC connection.
The inputs are protected against voltage surges and overcur-
rent. Voltages that exceed ±30V may cause the destruction of
the module. The inputs are protected against overcurrent by a
self-resetting fuse.
For the PLC connection, the following applies: a maximum
current of 2A (with a max. of 1A per contact) can be taken
from the +24V connections or fed through the 0V connec-
tions.
