Features:
- One short AT card is accommodated through a dedicated 98-pin interface.
- The module supplies +5 V, -5 V, +12 V and -12 V rails with current limits.
- INTF monitoring covers the -5 V, +12 V and -12 V auxiliary supplies.
This order number maps to ATM478, the M7-400 carrier used to add one legacy AT peripheral.
Backplane signals pass through the twin 120-pin connectors while local conversion distributes and supervises the AT supply rails.
Match the card dimensions, rail demand, driver and cooling method before reinstalling the peripheral in the expanded station.

- M7-400 stations can host a supported communication or peripheral interface supplied as a short AT card.
- Legacy automation computers can retain application-specific AT hardware while the carrier preserves the M7 bus chain.
- Service teams can isolate an INTF condition by checking the monitored auxiliary rails and the inserted peripheral load.
- The AT card plugs into the 98-pin connector while paired 120-pin interfaces continue the M7 backplane path.
- One short AT card can be installed, provided its electrical load and mechanical envelope remain within the module limits.
- The assembly combines left and right 120-pin backplane connectors with a dedicated 98-pin AT-card interface.
- A regulated 5 V DC backplane supply powers the interface and the installed short AT expansion card.
- Typical current consumption is approximately 0.12 A before any separately specified load from the fitted AT card.
- Approximate dissipation of 0.6 W keeps the base module's thermal contribution low inside the M7 station.
- The ATM478 configuration provides the mechanical and electrical carrier for one approved short-format AT card.
- A 25 x 290 x 230 mm module envelope must be accommodated without obstructing adjacent M7 components or airflow.
- Card function, resource allocation and connector assignment must be confirmed for the target M7 station before installation.
