The 2100-IS is a compact, desktop module that isolates and converts RS232 from a computer to RS422 or RS485 for communication to a field data logging system. Its driver and receiver meet EIA standards RS-422-A and CCITT recommendations V.11 and X.27, and are designed for multipoint transmission on long bus lines in noisy environments.
It includes thermal shutdown and over current limiting. The 2100-IS includes audible and fail safe alarms of communications failure, with selectable time delays. It is capable of interfacing to telephone modems, and RF modems.
It has independant power on both sides of the isolation barrier, making it suitable for working with many types of PCs and PLCs.
