How to Select an Interface Relay for PLC Outputs
A step-by-step guide to matching PLC output type, coil voltage and current, contact rating, and socket style when selecting an interface relay.
The ABB PM592-ETH-XC (order code 1SAP350200R0271) is an AC500-XC processor module with an Ethernet port, two selectable RS232/RS485 serial ports, an FBP fieldbus port, a 4GB flash disk, and an onboard display. Powered from 20.4-28.8V DC, IP20 rated, and weighing 0.155 kg, it is the extreme-conditions CPU for AC500 systems needing combined Ethernet and serial connectivity.
The combined Ethernet, dual RS232/RS485, and FBP ports let this CPU talk to a SCADA system, a legacy serial device, and a fieldbus master from one module, which is why it is specified over a single-port CPU when a cabinet mixes old and new field equipment. The onboard display and 4GB flash disk support local diagnostics and data logging without an external HMI. A standard-temperature installation can use the non-XC version instead of this XC-rated module.
