Electrical Connection

The CANOPEN bus module is plugged on the I/O terminal units TU517 TU517 and TU518 for Communication Interface Modules or TU518 TU517 and TU518 for Communication Interface Modules and accordingly TU509 TU509 and TU510 for Communication Interface Modules or TU510 TU509 and TU510 for Communication Interface Modules. Properly position the module and press until it locks in place.

The electrical connection of the I/O channels is established using the 30 terminals of the I/O terminal unit. I/O modules can be replaced without re-wiring the terminal units.

The terminals 2.8, 3.8, 2.9, 3.9 and 4.9 are electrically interconnected within the terminal unit and always have the same assignment, irrespective of the inserted module:

Terminals 2.8 and 3.8: process supply voltage UP = +24 VDC

Terminal 4.8: process supply voltage UP3 = +24 VDC

Terminals 2.9, 3.9 and 4.9: process supply voltage ZP = 0 V

Note

For a detailed description of the mounting, disassembly and electrical connection of the module, please refer to the System Assembly, Construction and Connection chapter AC500 (Standard).

Note

With a separate UP3 power supply, the digital outputs can be switched off externally. This way, an emergency-off functionality can be realized.
