Input/Output Characteristics of CI501-PNIO
The PROFINET Bus Module CI501-PNIO is used as decentralized I/O module in PROFINET
networks. The network connection is performed via 2 RJ45 connectors which are integrated in
the Terminal Unit. The Bus Module contains 22 I/O channels with the following properties:
● 4 analog inputs (1.0...1.3), configurable as:
– -10 ... +10 V
– 0 ... +10 V
– -10 ... +10 V (differential voltage)
– 0 ... 20 mA
– 4 ... 20 mA
– Pt100 , Pt1000, Ni1000 (for each 2-wire and 3-wire)
– 24 V digital input function
● 2 analog outputs (1.5...1.6), configurable as:
– -10 ... +10 V
– 0 ... 20 mA
– 4 ... 20 mA
● 8 digital inputs 24 V DC in 1 group (2.0...2.7)
● 8 digital transistor outputs 24 V DC (0.5 A max.) in 1 group (3.0...3.7)
● Resolution of the analog channels: 12 bits
The inputs/outputs are electrically isolated from the Ethernet network. There is no potential sep-
aration between the channels. The configuration of the analog inputs/outputs is performed by
software.
For usage in enhanced ambient conditions (e.g. wider temperature and humidity range), a spe-
cial XC version of the device is available.
