ABB 07 ET 83 A Procontic Cardfile

The 07 ET 83 A houses Procontic control modules in a rugged rack enclosure. This cardfile provides 8 slots for digital and analog I/O cards. It includes a passive backplane with power distribution rails.

Key Technical Specifications

Physical Dimensions and Construction

This cardfile measures 42.0 cm in length and 28.0 cm in width. Its total height reaches 16.0 cm including mounting feet. 07 ET 83 A weighs 3.2 kg for stable rack installation. The steel housing provides excellent mechanical protection and EMC shielding.

Moreover, the cardfile features a hinged front door for module access. Ventilation slots on the top and sides allow passive air circulation. You can mount the unit horizontally or vertically on a backplate.

Slot Configuration and Backplane Design

The passive backplane accommodates 8 Procontic modules in a single row. Each slot uses a 48-pin DIN connector for reliable contact. A heavy-duty bus bar distributes 24V DC power to all slots. Ground terminals connect directly to the enclosure for safety earthing.

Power Distribution and Wiring

A terminal block at the top accepts incoming 24V DC power supply. Two additional terminals provide +24V and 0V for daisy-chaining multiple cardfiles. Each slot receives fused power protection against short circuits. LED indicators on the backplane show power status for the entire rack.

Typical Application Scenarios

You can deploy 07 ET 83 A in ABB Procontic control cabinets with up to 8 modules. It also works well for central I/O racks near the CPU unit. This cardfile holds mixed configurations of digital and analog cards. Its 8-slot capacity suits small to medium-sized automation systems.
