Features:
- Eight relay outputs: the EM 222 adds contact-switched digital control points.
- 2 A channel rating: each output operates within the module’s published load limits.
- S7-22X assignment: the expansion module is tied to the installed S7-200 CPU family.
This module expands an S7-200 controller where relay contacts are required for the field-load interface.
AC or DC switching flexibility comes from the contact output, while protection and relay-life calculations remain load dependent.
Its cancelled lifecycle makes exact MLFB control and preserved wiring records especially important during legacy maintenance.
Apter Power can review 6ES7222-1HF22-0XA0 MLFB identity, condition, documentation, and legacy S7-200 sourcing requirements.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Channel count: eight digital outputs are provided.
- Contact interface: relay switching separates the control command from the field load.
- Current rating: the published maximum is 2 A per output within applicable limits.
- Load planning: voltage, inrush, switching rate, and relay life must be evaluated together.
- CPU scope: the EM 222 is intended only for S7-22X CPUs.
- Expansion role: it adds output points rather than executing the user program.
- Terminal continuity: retain the original channel and common mapping during replacement.
- Program alignment: the hardware configuration and field labels must remain synchronized.
- Lifecycle: Siemens lists the product as cancelled from 1 October 2017.
- Spare control: use the complete MLFB rather than EM 222 wording alone.
- Isolation: remove logic and field power before accessing relay wiring.
- Restart: test each commanded output with the real load under controlled conditions.
- Legacy machine control: maintain relay-switched actuators on installed S7-200 equipment.
- Mixed-voltage outputs: use isolated contacts where the documented load circuit requires them.
- Maintenance stock: support S7-22X systems that cannot yet be migrated to a current controller family.
