IC690ACC901 | GE Series 90-30 90-70 PLC Programming Lead

GE Fanuc IC690ACC901 Series 90-30 / 90-70 Mini Converter Kit RS-485 to RS-232

The IC690ACC901 (Model: IC690ACC901) is a high-performance serial communication converter kit designed for the legacy GE Fanuc Series 90-30 and 90-70 PLC systems. This kit acts as a signal bridge, converting RS-485 signals from the PLC's CPU port (SNP/SNPX protocol) to RS-232 signals compatible with standard PC serial ports. Unlike a simple passive cable, the IC690ACC901 features an integrated mini-converter that ensures voltage level compatibility and reliable data exchange over a distance of approximately 2 meters. It is the essential hardware link for engineers using Logicmaster, VersaPro, or Proficy Machine Edition to configure, program, and diagnose Series 90 controllers.
