Description
The 720 2001-01 is a bus connector that joins the internal backplane bus between adjacent SIMATIC S7-300 modules. Each signal, function, or communication module uses one to pass bus signals to the unit beside it, extending the rack and keeping the station's backplane link continuous across the assembly.
Cataloged by Siemens as order number 6ES7390-0AA00-0AA0, it is supplied as a replacement part for connectors lost or damaged during module changes. The connector weighs roughly 13 grams, uses a PC-GF20 glass-filled housing, and carries CE, UKCA, RCM, China RoHS, and EMC general product approvals.
Frequently Asked Questions
Which Siemens system uses this bus connector?
It is designed for SIMATIC S7-300 signal, function, and communication modules, transferring the internal backplane bus between adjacent modules on the rail.
Do I need one for every module?
Bus connectors are supplied with S7-300 signal, function, and communication modules, not with the CPU or power supply. This part replaces a missing or damaged unit.
Is this connector compatible with S7-1500 or ET 200SP?
No. It is specific to the SIMATIC S7-300 backplane bus. S7-1500 and ET 200SP use different module-interconnection systems and require their own connectors.
