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 6ES7960-1FB00-0AA5 is a synchronization module for the SIMATIC S7-1500H redundant PLC system, connecting the two H-CPUs over OS1 or OS2 single-mode fiber up to 10 km with an LC optical port at 1310 nm. It plugs into each CPU's sync slot and, engineered with STEP 7 TIA Portal V15.1 or higher, draws 0.83 W typical. Cable range runs from 2 m up to 10 km.
Choose this module when the two H-CPUs are separated by up to 10 km, for example across buildings on the same site or a plant-to-substation link; the single-mode OS1/OS2 fiber and 1310 nm optics are what make that distance possible. For CPUs within 200 m of each other, the multimode 850 nm sync module is the lower-cost choice.
