Siemens 6ES7214-1HG40-0XB0 SIMATIC CPU 1214C 14DI/10DO/2AI 24V DC

The Siemens 6ES7214-1HG40-0XB0 is a SIMATIC S7-1200 CPU 1214C compact programmable logic controller with DC/DC/relay configuration. It provides 14 digital inputs at 24 V DC, 10 relay digital outputs rated 2 A, and 2 analog inputs (0-10 V DC), all integrated on a single compact unit. The CPU operates from a 20.4-28.8 V DC supply and requires STEP 7 V20 or higher for programming.
