It is rated for 4 A continuous per channel up to 60 °C ambient, with no derating needed from 40 to 60 °C — the same 4 A limit holds across that band. ## Environmental and compliance highlights Operating range spans -40 to 70 °C. It carries EN 50155:2007 certification for rolling-stock applications (T1, Category 1, Class A/B), covering vibration, shock, and temperature cycling per sections 4, 5, and 12 of the standard. UL approval (File E239877), CE, KC, EAC, and RCM marks are all present, so the module is accepted in North America, Europe, Korea, the Eurasian Customs Union, and Australia/New Zealand without additional agency review. ## Input characteristics and wiring notes Signal \"0\" is recognized between -30 and +5 V; signal \"1\" between 13 and 30 V. The input resistance measures 48 Ω to 4 kΩ, so the module presents a light DC load to the sensor. It supports 2-wire proximity sensors directly, and the input filter is configurable: the hardware debounce for \"0\" to \"1\" transitions can be set between 1.2 ms and 4.8 ms, with the same range for \"1\" to \"0\". Maximum cable length is 1000 m shielded, 600 m unshielded — adequate for most industrial sensor runs but worth noting for long fieldbus or remote I/O drops. The module measures 40 mm wide, 125 mm high, and 120 mm deep, matching the standard S7-300 single-width format. It snaps onto the DIN rail and connects to the backplane bus via the module's own bus connector.","metaTitle":"Siemens 6AG1323-1BH01-2AA0 Digital Input Module, 8 DI","metaDescription":"Siemens 6AG1323-1BH01-2AA0 digital input module for S7-300. 8 channels, 24 VDC, 4 A per channel.
