Siemens 6ES7222-1HF22-0XA0 Programmable Logic Controller Module

Siemens 6ES7222-1HF22-0XA0 is an expansion digital output module (EM 222) for SIMATIC S7-200, designed to be used with S7-22X CPUs to provide eight relay outputs that can switch loads up to 2 A per channel. The module is an extension of the S7-200 family and is specified as "8 DA (relay outputs), 2 A," intended only for S7-22X CPU installations. Its compact footprint measures 45 x 80 x 62 mm and it weighs about 170 g, making it a space-conscious upgrade for compact automation panels. Electrical characteristics include a backplane bus supply of 5 V DC with a maximum input current of 40 mA and load voltages that support DC 24 V (nominal) with a 5–30 V range, or AC loads from 24 V AC up to 230 V AC with a 5–250 V range and a frequency range of 47–63 Hz; each switched output can handle up to 2 A. Typical applications involve expanding digital outputs to drive relays for auxiliary devices such as pumps, lights, or solenoid actuators in small PLC-based control systems.
