ABB AC500 PLC - 1.7.5.1.1 Intended Purpose; 1.7.5.1.2 Functionality

12 Terminal unit
13 DIN rail
Sign for XC version
1.7.5.1.1 Intended Purpose
The PROFIBUS DP bus module is used as decentralized I/O module in PROFIBUS DP net-
works. Depending on the used terminal unit the network connection is performed either via 9-
pole female D-SUB connector or via 10 terminals (screw-type or spring terminals) which are
integrated in the terminal unit. The bus module contains 22 I/O channels.
The inputs/outputs are electrically isolated from the PROFIBUS DP network. There is no poten-
tial separation between the channels. The configuration of the analog inputs/outputs is per-
formed by software.
For usage in extreme ambient conditions (e.g. wider temperature and humidity range), a special
XC version of the device is available.
● 4 configurable analog inputs (2-wire/single-ended) or 2 configurable analog inputs (3-wire/
differential)
Resolution 12 bits plus sign
● 2 analog outputs
Resolution 12 bits plus sign
● 8 digital inputs 24 VDC in 1 group
● 8 digital outputs 24 VDC in 1 group, 0.5 A max.
● Fast counter
● Module-wise electrically isolated
● XC version for usage in extreme ambient conditions available
