Product Description:

The AKT-DN-008-000 is a digital input terminal produced by Kollmorgen as part of the AKT IO Terminals series. Serving as an interface between field sensors and a controller, the unit converts switching signals into the internal data format required by an I/O bus coupler. By integrating eight discrete inputs in a compact body, it supports decentralized installation within control cabinets while maintaining the wiring style used across the Advanced Kollmorgen Terminal product line. It is suited to machine sections where multiple on and off signals need to be gathered close to the source.

The terminal provides 8 channels through a single-ended connection technique, meaning each sensor line is referenced to the common 0 V power contact rather than paired differential leads. Its input circuitry uses positive switching, so a high-side signal is detected when 24 V DC is applied to the point. The internal logic draws a standard bus current of 5 mA typical, which helps limit load on the upstream coupler. A 0 V power contact serves as the reference ground, and looped-through power contacts pass the supply to subsequent terminals without extra cabling.

For host-controller mapping, the device occupies a process image width of 8 inputs, and scan time remains at the standard 3 ms latency used in this I/O family, matching typical PLC cycle rates. The enclosure has an IP20 rating for cabinet installation, where protection against accidental finger contact is needed. At 55 g, the lightweight housing can be mounted in various positions and snaps onto DIN rail without placing significant strain on adjoining blocks. Pluggable wiring used across the Advanced Kollmorgen Terminal series simplifies installation, and the signal category remains strictly digital for predictable operation in mixed analog and digital racks.
