Siemens 6ES7212-1HE40-0XB0 Programmable Logic Controller Module

Siemens 6ES7212-1HE40-0XB0 is a compact SIMATIC S7-1200 CPU 1212C that combines DC/DC power with relay I/O in a single module. It includes 8 digital inputs at 24 V DC, 6 relay outputs rated 2 A, and 2 analog inputs (0–10 V), all housed in a compact CPU 1212C platform; its 8 DI, 6 DO, and 2 AI arrangement supports mixed discrete and analog sensing for straightforward control logic. The unit is powered from a DC supply of 20.4–28.8 V DC and provides 100 KB of program and data memory for small automation tasks. The DC/DC/relay configuration indicates that the CPU can be powered by a DC source while driving relay outputs for simple control tasks, making it suitable for compact automation applications and small machine control panels. This CPU is designed for straightforward integration within SIMATIC S7-1200 project environments, offering a compact footprint, a ready-to-wire I/O configuration, and suitability for space-constrained installations.
