Product Description:

The AKT-DN-004-000 digital input terminal is produced by Kollmorgen and belongs to the AKT IO Terminals series. As a member of the Advanced Kollmorgen Terminal product family, it serves as a compact interface that brings field signals onto an EtherCAT backbone. In industrial automation, it translates simple switch or sensor states into controller-readable bits, letting machine tools, conveyors, and packaging lines capture local status while keeping wiring short.

The slice is a 4-channel digital input module that runs from a 24 V DC nominal supply. Four dedicated +24 V points share this supply and accommodate up to four 2-wire sensors, matching the channel count. The input electronics follow the IEC 61131-2 Type 1 characteristic, so the terminal meets the current thresholds and delay profiles expected by PLC programs. Scanning latency is rated at Standard (3 ms), meaning a transition on the terminal is reflected in the process image within that window. Environmental sealing is IP20, which is suitable for closed control cabinets. No address switches are fitted, so node identity comes solely from the physical order on the terminal strip. The process image width equals four inputs, and the low quiescent draw eases backplane loading.

The terminal can be installed in any orientation because its specified mounting position is variable, which helps designers place I/O above drives or beside power supplies without airflow concerns. Within the bus segment, the module itself draws only typical 3 mA, allowing dozens of slices before auxiliary feeds are required. Classified under the digital signal category, the AKT-DN-004-000 adds minimal weight to a rail. At 50 g, it is light enough for vibration-sensitive enclosures yet sturdy enough to withstand repeated plug and unplug cycles during maintenance.
