PLC | Siemens | 6ES7241-1CH30-1XB0 SIMATIC S7-1200 CB 1241 6ES7 241-1CH30-1XB0

Product Description: 6ES7241-1CH30-1XB0

The 6ES7241-1CH30-1XB0 is a high-feature digital input module for the SIMATIC S7-1200 PLC. It provides sixteen isolated 24 V DC inputs in a single 45 mm- wide housing. Each channel offers built-in diagnostics (short-circuit, wire- break, overvoltage) and user-selectable debounce filtering, delivering reliable detection of PNP/NPN sensor signals. Snap-on mounting to the CPU’s backplane bus ensures seamless power and data transfer, making it ideal for compact automation systems requiring high- density, diagnostic I/O.
