Product Description:
The AKT-DNH-004-000 is a digital input terminal produced by Kollmorgen and assigned to the AKT IO Terminals series. As a member of the Advanced Kollmorgen Terminal family, it is intended to bring four discrete field signals into a machine controller’s process image through the EtherCAT backplane. By converting 24 V sensor levels into logic-level data, the unit supports rapid status acquisition for industrial automation tasks such as safety interlocks, part detection, or operator push-button monitoring. It is suited to applications where simple on or off device states must be transferred to the control system without local signal conditioning.
This module operates on a nominal supply of 24 V DC and provides 4 inputs that are internally referenced to the common field potential. Each channel is filtered at 0.2 ms, which helps prevent spurious transitions from reaching the PLC. Compliance with IEC 61131-2 keeps the input behavior consistent with common automation practices for switching thresholds. The process image is refreshed within 3 ms, which is suitable for general-purpose logic sequences that do not require sub-millisecond reaction. With a process image width mapped to one byte, all four bits arrive simultaneously at the controller, allowing deterministic scan alignment and straightforward signal handling inside the control program.
An enclosure rating of IP20 restricts the device to clean, cabinet-mounted locations. Tool-free, pluggable wiring keeps installation orderly and makes connection changes easier to handle at the terminal strip. The terminal supports 2-wire sensor connections, so only power and signal conductors are needed for each input. Four front-facing status indicators, identified as 4 signal LEDs, provide immediate confirmation of field state. Because the design uses no address or configuration switches, setup is limited to slot position recognition in the EtherCAT node list. Its compact terminal format also helps keep mixed I/O assemblies organized when several signal types are installed side by side on the same backplane.
