1
I/O bus (10 pins, female) to connect the first terminal unit
2a Plug (2 25 pins) to connect the inserted communication interface module
2b Plug (2 19 pins) to connect the inserted communication interface module
3
With a screwdriver, inserted in this place, the terminal unit and the adjacent I/O terminal unit
can be shoved from each other
4
2 holes for wall mounting
5
10 terminals for connection with the bus system
6
30 terminals for signals and process supply voltages (UP and UP3)
7
DIN rail
The communication interface modules plug into the terminal unit. When properly plugged-in,
they are secured with two mechanical locks. All the connections are established via the terminal
unit, which allows removal and replacement of the communication interface modules without
disturbing the wiring at the terminal unit.
The terminal units TU517 and TU518 are specifically designed for use with AC500/S500 com-
munication interface modules (e. g. CI581-CN, CI541-DP):
● CANopen communication interface modules
● DeviceNet modules
● PROFIBUS DP communication interface modules
