Product Description:

The AKT-DNH-008-000 is a digital input terminal produced by Kollmorgen within the AKT IO Terminals series. As a member of this series, the unit collects discrete field-level signals and forwards their logic states to a higher-level controller through the backplane bus. By concentrating eight channels in a single 12 mm housing, the module conserves cabinet space and simplifies decentralized I/O expansion in industrial automation lines and compact control panels.

The terminal operates on a nominal supply of 24 V DC and presents a process image that is eight bits wide, matching the physical channel count. Each channel includes an input filter of 0.2 ms to suppress contact bounce before the signal is sampled by the controller during normal scan operation. Input circuitry uses Positive switching, so sensors must pull the line high against the common 0 V reference. Typical internal consumption from the K-bus is only 5 mA typ., minimizing current draw from the host coupler. Signals enter through a single-ended connection technique. Field conductors can be inserted and removed quickly through pluggable wiring, and the looped-through power contacts distribute field supply to adjacent terminals without additional jumpers.

Environmental and mechanical data complete the profile. The housing carries a protection class of IP20, indicating finger-safe design for mounting inside an enclosure. With a mass of just 55 g, the module adds minimal load to DIN rail structures. Reliable operation is specified up to a relative humidity of 95% without condensation, and signal integrity is referenced to the 0 V power contact. The terminal allows a variable installation position, so it can be mounted in any orientation, and its standard operating speed category of 3 ms supports ordinary PLC scan and update cycles in routine control tasks.
