The ABB 1SAP170400R0001 is the order code for the CM574-RS communication module of the AC500 family: two freely configurable serial ports supporting RS232 and RS485 interfaces for point-to-point and multi-point communication with third-party devices. Distributor datasheets describe it as two serial interface channels with 20 mA current loop and HSI options, freely configurable in AC500 toolsets, and listings across major distributors record weight around 0.4 kg with international stock. Refurbished and new units are offered with multi-year warranty. Use CM574-RS to connect bar-code readers, drives, meters or legacy serial equipment to an AC500 CPU.
