Applications

I/O adapter 520ADD02 for connecting more than 16 RTU520 I/O modules to the

RTU520 or RTU540 to an I/O bus with RS485 or fibre optic connection.

The adapter can also be used to extend the WRB I/O bus in decentralised I/O applications.

The maximum distance is up to 2 www.cniacs.com kilometres and the distance between the I/O adapters needs to be more than 30 cm.

In addition, I/O adapter 520ADD02 can be used as a stand-alone module to extend the RTU560 I/O modules (e.g. 23BE40. 23BE40. 23BE40. 23BE40. 23BE40. 23BE40. 23BE40. 23BE40. 23BE40. 23BE40).

(e.g. 23BE40. 23BE50. 23BA40) to the RTU540.

The module is available in two versions (standard)

– R0001: RS485

– R0002: RS485 and glass fibre optics, 840 nm
