Other Fieldbus Repeaters

Modbus Plus(MB+) Repeater

Modbus Plus(MB+) Protocol Repeater

The Modbus Plus Repeaters are designed to be used in Modbus Plus field bus cable segments,provide a link connection between two Modbus Plus segments. The Repeater contains two electrical interface for Modbus Plus.The electrical port of the Repeater has the same network connections, specifications and restrictions as other Modbus Plus devices, and must be treated accordingly.

The Modbus Plus bridge device is powered by 24V DC voltage. A redundant feed increases operational safety.

For the Modbus plus repeater using protocol repeater transmission technology, the modules can be connect MB+ cable segments ,You require a repeater in the following situations:

--When there are more than 32 stations (including repeaters) connected to the bus

--When electrically isolated bus segments are required or

--When the maximum cable length of a segment is exceeded

6 multicolored LED indicate the current operating status
