- Description
The Siemens 6ES7924-0CC21-0AA0 is a SIMATIC TOP connect TPA connection module with a 3-tier, 30-terminal screw-terminal block for analog modules on a SIMATIC S7-300, supplied as a spare part with no signalling LED. It links analog field wiring to the S7-300 front connector module through a 16-pole IDC cable, mounted on a 35 mm DIN rail.

Selection Notes
Siemens lists this module as a spare part for existing SIMATIC S7-300 analog I/O installations rather than a new-design item, so specify it primarily to replace or expand an already-installed TPA connection. Screw terminals torqued to 0.4 ... 0.5 N·m accept 0.5 ... 2.5 mm² conductors, a wider minimum cross-section than the push-in S7-1500 TPA’s 0.2 mm² floor. Without an LED, verify analog channel wiring at the controller or engineering tool rather than at the terminal block.
