It carries 28 screw-type terminals — 8 I/O, 10 L+, 10 M — rated at 1 A per terminal, 4 A total. ## Wiring and installation constraints Terminals accept stranded wire from 0.5 to 2.5 mm²; a 3.5 mm screwdriver blade is specified for tightening. Up to two wires per connection are allowed, provided the combined cross-section fits within a single ferrule. Maximum wire length from the front connector module to this connection module is 30 m. No shield connection or PE connection is provided on this module — shield grounding must be handled at the I/O module or cabinet entry. An end cover plate is not required.","metaTitle":"Siemens 6ES7924-0CH20-0BA0 Connection Module, SIMATIC S7-300/1500, 76 mm","metaDescription":"Siemens 6ES7924-0CH20-0BA0 connection module for SIMATIC S7-300/1500 digital I/O. 76 mm length, 28 terminals, screw-type, 1 A rated.
