2-6.2 New Repeaters

New repeaters are identified by the fact that they are mounted in a DIN rail mount enclosure. Neither

have a separate earth terminal as it is a 24 V AC powered device, however the 24 V supply must be

earthed on the 0V side for safety and to make use of the So Earth feature.

• The IR12 is the current dual channel and dual baud rate repeater

• The IR11 is the current single channel dual baud rate repeater

• The IR12 and IR11 are fully isolated and both Port 1 and Port 2 oer the same level of protection.

That means that both Ports 1 & 2 can be used for the remote site connection.

The earth on the IR12 must be connected to the so earth terminal.

2-7 End of Line Termination (EOL)

Due to specific design parameters relating to the bias of the network and network configurations, the

Primary network has currently no need for End of Line Terminations (EOL).
