ISC-9440 supports conversion between one master station RS232/485 and 4 slave stations RS485

Isolated RS232/485 to 4-Channel RS485 Hub Effectively isolates interference between slave RS485 ports, and between slave RS485 ports and the master RS485 port. Both master and slave RS485 ports support up to 256 slave stations with powerful signal amplification capability. It can realize repeater function, network expansion and electrical isolation for RS485 networks. It can also be used as an active isolated RS232-to-RS485 converter. Wide voltage input, DIN rail mountable. RS485 reverse connection indicator: the indicator stays on when the wiring is reversed.
