  • Description

The Siemens 6ES7921-3AG00-0AA0 is a SIMATIC TOP connect front connector module for S7-300 analog I/O modules. It carries the signal wiring through a single 16-pole IDC cable connection and feeds power through screw-type terminals rated 24 V DC, 1 A, torqued to 0.4-0.7 N·m, with one L+ and one M terminal. It plugs directly into the analog module in place of the factory front connector.

Selection Notes

With only one L+/M terminal pair, this connector matches analog modules that draw a single supply feed rather than the multi-terminal digital variants in the same TOP connect family. Screw terminals give a documented 0.4-0.7 N·m tightening torque on that feed, useful where the build sheet requires a recorded torque value; pick the spring-terminal version instead when analog cards are swapped often and tool-free wiring speed matters more.
