Product Description:
Kollmorgen's AKT-AN-820-000 belongs to the AKT IO Terminals series and functions as an analog input module for the Advanced Kollmorgen Terminal family. Installed on distributed I/O stations, it converts field current loops from sensors into digitized data that the central controller can interpret. The module ties into the system backplane through the standard bus, allowing its measurement data to appear directly in the PLC process image without separate wiring. In industrial automation, this unit provides compact, high-density signal acquisition for motion platforms and general machine control where multiple analog loops must be read in limited cabinet space.
The module offers 8 channels of acquisition, so eight transducers can be monitored on a single slice. Each channel is resolved to 12 bits, producing 4,095 discrete codes in two's complement format for signed engineering values. The permissible signal span is 0–20 mA, and an internal input resistance of 85 Ω keeps the burden on loop drivers low. Measurement uncertainty stays within ±0.3% of full scale, while a maximum common-mode tolerance of 30 V helps protect the circuits from ground shifts often found in large machines. These limits describe the level of analog accuracy available to the control program during closed-loop tasks.
The housing clips onto a 35 mm EN 50022 rail. Its power contacts are passed through, so adjacent modules can daisy-chain the supply arriving via the standard bus. Typical internal demand is 105 mA, and the reference ground is tied to the 0 V power contact to help maintain low-noise measurements. The process image presents 8 × 16-bit words, with an optional 8 × 8-bit byte format available to the controller. The protection class is IP20, and the surge-voltage resistance is 30 VDC for use in control enclosures.
