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 Siemens 6ES7194-2AA00-0AA0 is a 4-pole M8 power connector with a male contact insert for wiring the 24 V DC supply into SIMATIC ET 200AL remote I/O stations. Its plastic housing is rated IP65/67, accepts screw-terminated conductors from 0.14 to 0.5 mm2, and fits cable diameters from 4 to 5.5 mm.
This is the male contact insert; it mates with the socket-insert connector on the other side of the 24 V DC feed into an ET 200AL station. The plastic housing keeps the part light for standard machine-floor mounting, while the metal-housed ET-CONNECTION connectors cover the shielded data line on the same stations.
