Siemens 6ES7222-1HD22-0XA0 Programmable Logic Controller Module

Siemens 6ES7222-1HD22-0XA0 is a SIMATIC S7-200 four-channel relay output module (EM 222) that mounts on the S7-200 backplane. Each of the four relay outputs is rated for up to 10 A, allowing control of motors, solenoids, heaters, or other high-current devices. The module switches DC loads from 5 to 30 V and AC loads from 5 to 250 V, with DC loads commonly using 24 V and AC loads up to 230 V; the L+ DC supply and L1 AC paths respectively power the switched circuits. It draws 30 mA from the 5 V backplane bus, and typical power loss is about 4 W. Compatible with S7-200 CPUs, including 22x models, this EM 222 module is suitable for compact automation panels where multiple discrete outputs are required.
