The Siemens 6ES7924-0CC00-0AA0 is a TPA terminal block used in the SIMATIC S7-300 and ET 200M distributed I/O systems. It provides the wiring interface between field devices and the I/O module front connector.
Integration note
Mounts on the standard DIN rail alongside the I/O module. The TPA block accepts the pre-wired front connector from the field cable; verify the connector keying matches your specific I/O module type before wiring. No special tools beyond a screwdriver for the spring-cage terminals.
