Buyer question: what must match?
Start with the complete TM3AI4 code, not only a family name. Compare the fitted item's nameplate with the proposed TM3AI4 supply, rating, terminals, mounting and accessories. A close-looking suffix can change the electrical or mechanical interface.
For TM3AI4, document the actual panel or machine duty and any associated drawing. Confirm configured signal type, scaling and PLC compatibility. When the application is safety-related, have a qualified engineer assess the complete function and applicable design requirements.
At the equipment
Photograph the existing TM3AI4 installation before removal. Record the cable labels, environmental exposure, protective devices and available clearance. If TM3AI4 is part of an automation assembly, back up relevant settings and record the matching controller, drive or accessory revision.
Do not infer drop-in interchangeability from the image or the TM3AI4 family description. Confirm the current manufacturer data and installation manual for the exact TM3AI4 variant; compare the delivered nameplate before work begins.
Order and commissioning notes
The purchasing request for TM3AI4 should state the full code, quantity, required accessories and the intended equipment tag. For legacy equipment, confirm regional availability and lifecycle status rather than assuming that a historically used TM3AI4 remains the preferred replacement.
After qualified personnel install TM3AI4 under site isolation procedures, check wiring, settings and functional response against the approved drawing. Keep the test record with the TM3AI4 designation for subsequent service.
Related-looking model codes
These 11 TM3A-pattern codes resemble TM3AI4 and are indexed on this representative page instead of receiving separate pages in this publishing set. They are not declared equivalent to TM3AI4; verify every complete code and option string.
Release decision
Release the TM3AI4 order only after the exact rating, matching accessories and fit are confirmed. Retain the TM3AI4 data record and commissioning evidence so future maintenance can distinguish this exact variant from adjacent codes.
