The TPA 3-tier Connection Module (6ES7924-0CC21-0AA0) is a connection module from Siemens designed for analog modules of the SIMATIC S7-300 system. \nIt features screw terminals (morsetto a vite) without LEDs for signaling and a 16-pole IDC cable connection, VPE=1 unit. The module serves as an interface \nbetween the connecting cables from field peripherals and the SIMATIC S7-300 system. It is mounted on a DIN rail and is part of the SIMATIC TOP connect system, \nproviding fast and secure cabling. This reduces wiring costs and significantly minimizes cabling errors. The net weight is 0.180 kg, and the packaging\n dimensions are 5.80 x 7.80 x 6.80 cm. It is used in industrial automation systems, particularly for managing and connecting analog signals.
