Remanufactured GE-Emerson IC690ACC903 Series 90-70 RS-485 Port Isolator

The GE-Emerson IC690ACC903 Series 90-70 RS-485 Port Isolator provides the basic functionality of the IC655CMM590 Isolated Repeater/Converter except for the converter function. The Port Isolator features 500V of isolation in a compact package servicing all IC693, IC697, and IC200 PLC product lines. The Port Isolator connects either directly to a 15-pin RS-485 serial port or through the optional 12in (30cm) extension cable, IC690CBL003, which may be ordered separately. The extension cable is intended for applications where direct connection to the port is obstructed by surrounding equipment or when it is not acceptable for the Port Isolator to protrude from a PLC module. The Port Isolator can operate in either single or multidrop mode, selected by a recessed slide switch on the top of the module.
