It provides 72 push-in terminals in a single level, arranged at the top of the enclosure, for wiring field signals to the backplane. Rated at 24 V DC and 1 A, it includes an infeed function for distributing power to connected modules — useful for keeping the 24 V bus clean without a separate distribution block. Mounts on either 35 mm or 15 mm DIN rail, in any position, which gives flexibility in crowded cabinets where rail profiles vary. ## Wiring and termination details Push-in terminals accept stranded wire from 0.2 to 2.5 mm² — typical for analog signal loops (4-20 mA, thermocouple, RTD). Up to two wires per connection are allowed, with the cross-section sum limited by ferrule capacity. The maximum wire length between the front connector module and this connection module is 30 m, which covers most panel-to-field junction box runs. No shield connection or PE connection is integrated on this module — shield grounding must be handled at the field device or via a separate terminal block. Enclosure is grey, dimensions 130 mm wide × 76 mm high × 60 mm deep. Flammability rating UL 94 V1. No end cover plate required.","metaTitle":"Siemens 6ES7924-2CC20-0AC0 Connection Module, 72 terminals,","metaDescription":"Siemens connection module for SIMATIC S7-1500 analog I/O. 72 push-in terminals, 1 A rated, 24 V DC infeed.
