The RS-485 Repeater/Splitter provides a means of creating electrically separate RS-485 bus segments. The unit provides bi-directional half-duplex communication between a Master RS-485 port and up to five Slave ports.
The unit has three power supply inputs: K2 & K3 (Master), K5 (Slaves 1-4), and K8 (ISO Slave). The slave ports (Slaves 1-4) may be electrically isolated from the Master power circuit. The ISO Slave port may be electrically isolated from Slaves 1-4 and the Master channel. Alternatively, Slaves 1-4 and/or ISO Slave may be driven from the same power supply as the master power circuit.
The RS-485 Repeater/Splitter may be installed inside a Pertronic fire alarm control panel, or it may be installed in a stand-alone enclosure.
