Purpose
The RPT-485W is an ACS annunciator loop repeater for twisted pair wiring which extends the loop length and
node capacity of the EIA-485 Annunciator Loop. The RPT-485W electrically isolates the EIA-485 Annunciator
Loop.
Features
Extends EIA-485 distances in 4000 ft. increments.
Allows additional boosted EIA-485 loops.
Each boosted loop increases annunciator node capacity by 32.
EIA-485 branch connections are electrically isolated to prevent ground fault detection problems.
Two LEDs indicate data reception.
Removable terminal blocks.
A variety of mounting options.
