Overview Manuals Selection Installation Service Checks Applications

Features:

  • Falcon ET-125 interface: 16-function-key operator-interface version.
  • RS-422 serial communication: interface designation for this configuration.
  • Machine-oriented visualization: Falcon range for visualization and PLC tasks.
ET-125-RS422 is the ET-125 member of the STAHL Falcon operator-interface range. Its 16-function-key arrangement distinguishes this version within the Falcon selection.

The RS-422 designation identifies the serial interface version. Match the communication arrangement in the installed automation system before selecting a replacement unit.

Falcon operator interfaces are used for machine-oriented visualization and PLC tasks. Keep the full ET-125-RS422 code with the installed interface context because Falcon packages can include separate power, isolation, and cable components.

Apter Power supports documentation review, quotation, and procurement for the STAHL ET-125-RS422 HMI Terminal.

  • Compare the removed item with the installed system record.
  • Do not treat related hardware as automatically interchangeable.
  • Installation of ET-125-RS422 should be carried out by qualified personnel.
  • Follow the approved site isolation and handling procedure.
  • Confirm the installed connection arrangement before energising.
  • Record the exact ET-125-RS422 identity before service work.
  • Inspect the removed unit and its connection context for relevant differences.
  • Follow the host-equipment service procedure for functional checks.
  • ET-125-RS422 is supplied for maintenance and exact-model sourcing support.
  • Use it only after the installed equipment context has been reviewed.
  • Apter Power can assist with documentation and quotation enquiries.
Description
ET-125-RS422 is an R. STAHL HMI interface terminal identified on the equipment label by the ET-125-RS422 type code. The RS422 designation is part of the installed communication identity and should travel with the unit record.

When servicing an existing interface panel, ET-125-RS422 must be considered in relation to its existing HMI system and serial communication connection. That keeps the sourcing decision focused on the intended terminal role rather than a general panel-computer description.

For a controlled maintenance enquiry, ET-125-RS422 gives the exact type reference needed to compare the removed equipment with its host system documentation. Preserve the label details and serial connection context before planning a change.
Alternative Names

Technical notes
ET-125-RS422 carries an RS422 interface designation, making the installed serial-communication context its key boundary. A terminal that fits a panel opening can still be unsuitable if the host HMI connection differs. Stop the change review until the existing terminal type and serial interface arrangement are both documented.

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.
When may STAHL ET-125-RS422 be used in a hazardous-area operator-station application?
Use ET-125-RS422 only after checking the actual product label, installed enclosure and site classification against the required zone approval. The Falcon ET manual describes the family for hazardous environments, but the individual device marking determines the approvals that apply to that unit.
What should a technician do if an ET-125-RS422 has a cracked enclosure, damaged front panel or compromised sealing surface?
Remove it from service and escalate it for an approved repair decision. The supplied Falcon manual warns that visible damage can compromise explosion protection and directs users to return damaged equipment to the manufacturer for repair.
How should an ET-125-RS422 communication fault be investigated before ordering a replacement?
Confirm the installed interface is RS-422, then record the connected controller, cable route, connector condition and the terminal’s configured application. An operator-terminal fault can otherwise be confused with a field wiring, controller or configuration fault.
What supply check is required before energising an ET-125-RS422 after service work?
Verify the actual terminal wiring and supply against the unit label and approved installation documentation. The supplied manual gives the ET family a nominal 10.8 VDC supply range, but site wiring and the specific unit marking remain the controlling references.
Why should the original ET-125-RS422 configuration be retained before replacement?
The terminal is an operating and monitoring device, not merely a display. Retaining the existing project, display setup and connected-control-system records helps restore the operator interface without changing the machine’s established functions.
Can an ET-125-RS422 replacement be selected solely from the “ET-125” family designation?
No. Confirm the complete ET-125-RS422 designation, communication interface, hazardous-area marking, installed configuration and physical connection arrangement. A shared ET-125 family name does not establish an interchangeable replacement.
