More Information

Overview Manuals Relay Output Design S7-200 Integration Legacy Service Product Applications

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.
Description
For relay-switched field loads on a SIMATIC S7-200 station, 6ES7222-1HF22-0XA0 adds eight digital output channels. The EM 222 is designed for S7-22X CPUs, and its relay contacts can switch AC or DC field circuits within the published contact limits.

Each output of 6ES7222-1HF22-0XA0 is rated up to 2 A within the published relay and grouping limits. That contact-based architecture can switch AC or DC loads, but load voltage, inrush current, duty cycle, and relay life remain part of the cabinet design rather than interchangeable channel details.

Because 6ES7222-1HF22-0XA0 has been cancelled by Siemens, its value is in maintaining installed S7-200 systems with an exact MLFB match. A replacement plan should preserve CPU family, terminal assignment, supply grouping, output-load characteristics, and the saved program documentation.

Technical notes
6ES7222-1HF22-0XA0 is an eight-channel relay-output EM 222 for S7-22X CPUs, not a 24 V DC transistor module. Relay contacts have load, inrush, switching-frequency, and life limits; de-energize both logic and field circuits before wiring, and preserve the original terminal map when servicing a cancelled S7-200 station.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can 6ES7222-1HF22-0XA0 be used with every SIMATIC CPU?
No. Siemens specifies the EM 222 for S7-22X CPUs. A different controller family needs its own supported expansion module and hardware configuration.
What loads can the relay outputs of 6ES7222-1HF22-0XA0 switch?
They can serve AC or DC circuits within the published contact limits. Check steady current, inrush, switching frequency, suppression, and expected relay life for the actual load.
How should 6ES7222-1HF22-0XA0 be diagnosed when a program command changes but the load does not?
Compare the module indication with safely measured field power, then isolate the external wiring and load before concluding that the relay output has failed.
How should 6ES7222-1HF22-0XA0 be wired during a replacement?
Isolate logic and field power, label every conductor and common, transfer the original terminal map one point at a time, and test each commanded load before automatic operation.
What does cancellation mean for maintaining 6ES7222-1HF22-0XA0?
Plan exact-MLFB service stock and preserve a verified backup of the S7-200 program and wiring documentation. Cancellation does not establish interchangeability with a newer output module.
How can relay life be protected on 6ES7222-1HF22-0XA0?
Keep loads within the specified electrical limits and apply the suppression required by inductive devices. Excessive inrush or rapid switching can shorten contact life even below the 2 A steady-current figure.
