Product Details

1203‑GK1 is Rockwell Allen‑Bradley RIO‑SCANport communication adapter.

It realizes protocol conversion between PLC Remote I/O network and SCANport interface of PowerFlex drives,realizing drive start‑stop,frequency setting,fault feedback and parameter access via RIO link. Configurable by DIP switch for baud rate and station address,powered by SCANport bus without extra power supply. Module failure will result in drive communication loss,control failure and production shutdown,widely used for old‑site PowerFlex drive overhaul and spare‑part replacement.
