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 6ES7960-1AA04-5AA0 is a fiber-optic (FOC) patch cable for the SIMATIC S7-400H fault-tolerant CPU, supplied in a 1 m length. It links the two synchronization modules that keep a redundant S7-400H CPU pair's memory and process image in step. At 28 g, it is the short-distance option for racks mounted in the same cabinet.
Choose this 1 m cable when both CPU racks of the redundant pair sit in the same cabinet; the 2 m or 10 m versions of the same cable are the fit for racks mounted further apart or in adjacent cabinets.
