Brand: SIEMENS
SKU: 312994785

Eight-Channel Relay Output Signal Module

6ES7222-1HF32-0XB0 expands a SIMATIC S7-1200 station with eight electromechanical relay outputs. Its contacts support compatible loads from 5–30 V DC or 5–250 V AC, allowing one module to serve mixed-voltage panel devices.

Each channel can switch up to 2 A with a resistive load. Confirm inrush current, switching frequency, external protection and relay service life before connecting contactors, alarms, valves or auxiliary circuits.

Use and Application

The module converts PLC commands into ordinary relay switching for contactors, indicators, horns, small actuators and isolated interfaces in packaging machines, conveyors, utility skids and mixed-voltage control panels.

FAQ - SIEMENS 6ES7222-1HF32-0XB0

Q1. Which output technology does 6ES7222-1HF32-0XB0 use?
6ES7222-1HF32-0XB0 uses eight electromechanical relay outputs, allowing compatible AC and DC loads to be switched.

Q2. What voltage range can 6ES7222-1HF32-0XB0 switch?
The relay contacts of 6ES7222-1HF32-0XB0 are specified for 5–30 V DC or 5–250 V AC within the published load limits.

Q3. Is 6ES7222-1HF32-0XB0 suitable for high-speed pulse output?
No. With switching delays up to 10 ms, 6ES7222-1HF32-0XB0 is intended for ordinary relay switching rather than high-speed pulse generation.

Q4. Does 6ES7222-1HF32-0XB0 need external circuit protection?
Yes. Siemens states that short-circuit protection for 6ES7222-1HF32-0XB0 must be provided externally and selected for the connected load.

Q5. What should buyers verify before ordering 6ES7222-1HF32-0XB0?
Confirm the complete 6ES7222-1HF32-0XB0 article number, AC or DC load voltage, current, inrush characteristics, switching frequency and expected relay life.
