  • Description

The Siemens 6ES7921-3AC00-0AA0 is a SIMATIC TOP connect front connector module built for S7-300 2 A digital output modules. It carries the load-side wiring through a single 16-pole IDC cable connection and feeds power through spring clamp terminals rated 24 V DC, 1 A per contact. It plugs directly into the output module in place of the factory front connector.

Selection Notes

This variant is scoped specifically to 2 A output modules rather than the general digital I/O family, so it is the correct pick whenever the target module's data sheet calls for a 2 A-rated front connector instead of the standard 1 A part. Spring clamp terminals connect the L+/M supply wiring without a screwdriver, useful when several output modules are wired in one pass; use the screw-terminal version where a recorded tightening torque is required on the supply connection.
