Siemens S7-300 module power cable

This new internal power cable is built specifically for the Siemens S7-300 6ES7321-1BH50-0AA0 module. It supplies the correct connection for that part in automation cabinets and control panels. The cable arrives in its original box, ready for installation. Buyers who need a cable for a different module or a generic power lead cannot use this item.

Exact fit for 6ES7321-1BH50-0AA0

The only specification that matters is the precise module match: this cable is made for the 6ES7321-1BH50-0AA0. No other pin-out, voltage keying or length is supported. Verify the module part number on your hardware before ordering; a mismatch will prevent the cable from seating or powering the unit.

Questions about this item

What does the 300-series designation mean when this cable is installed in a working S7-300 rack?

The 300 in the module number identifies the Siemens S7-300 PLC family; this cable is built to match that rack's back-plane power pins and voltage rails.

Which connector standard does this cable use and what does it limit in daily operation?

It uses the proprietary Siemens S7-300 back-plane connector, which limits the cable to powering only 6ES7321-1BH50-0AA0 digital input modules in that chassis.
