Siemens 6ES7 274-1XH30-0XA0 Simatic S7-1200 I Simulator

Siemens SIMATIC S7-1200 simulator module SIM 1274, part number 6ES7274-1XH30-0XA0, provides 14 digital input points for 24 V DC to accompany CPU 1214/1215 in the SIMATIC S7-1200 family. This 14‑DI input simulator is designed to emulate external digital signals for testing ladder logic and I/O responses without needing real sensors, making it ideal for development, debugging, and training environments. Verified details from Siemens catalogs show the model supports 14 digital inputs at 24 V DC and is intended for use with CPU 1214/1215, aligning with the SIM 1274 family of digital input simulators. The module is a part of Siemens’ SIMATIC S7-1200 ecosystem and enables realistic input-state testing by manually toggling the 14 input switches, facilitating rapid validation of control logic and sequence operations in a controlled lab or production planning setting.
