ISC-1212-I
Industrial RS-422/485 Repeater with Isolation
 

Overview

The ISC-1212-I is a RS-422/485 repeater which boosts the RS-422/485 signals to extend the reach distance up to 4000 ft (1200m) and increase the maximum number of connection up to 128 nodes. With a special circuitry, ISC-1212-I is able to automatically detect the data flow and switch the direction of the data lines accordingly. “Auto baud rate detector” enables ISC-1212-I to automatically configure RS-422/485 signals to any baud rate without external switch setting. Build in opto-isolations on ISC-1212-I provides 3000VDC of isolation to protect the host computer from destructive voltage spikes on the RS- 422/485 data lines. ISC-1212-I also offers internal surge-protection on the data lines. The internal high-speed transient suppressors on each data line protect the module from dangerous voltages levels or spikes. Therefore, the ISC-1212-I is a reliable RS-422/485 repeater and can satisfy most demand of operating environment.
