Siemens 6ES7214-1AC01-0XB0 Digital Input Module

Siemens 6ES7214-1AC01-0XB0 is a SIMATIC S7-200 CPU 214 compact controller with 24 I/O points, comprising 14 digital inputs and 10 digital outputs. It runs on an integrated 24 V DC power supply and provides a built-in RS-485 interface (MPI/PPI/Freeport) for serial fieldbus communication. The module includes 4 KB of user memory for the control program and supports 24 V DC digital I/O, with each of the 10 outputs rated up to 0.75 A. The 14 digital inputs are 24 V DC sinking type, suitable for direct connection of common-supply sensors, while the 10 digital outputs can switch loads within the stated current limit. This CPU 214 variant is designed for compact automation tasks and is commonly used in small machines and control panels requiring a self-contained PLC with straightforward connectivity and a compact footprint.
