Product Description:
The AKT-AN-400-000 belongs to the AKT IO Terminals series from Kollmorgen and is an analog input module in the Advanced Kollmorgen Terminal family. It accepts temperature signals from industrial thermocouples and forwards digital values through the series backplane so a controller can monitor process heat, cooling loops, or environmental chambers. In decentralized I/O stations, this module occupies minimal panel depth, allowing temperature acquisition to be placed close to the sensor and reducing wiring runs inside automated machines. Placing signal conversion near the sensing point can also help keep low-level thermocouple signals away from longer cabinet runs that may introduce electrical noise.
The module samples up to 4 channels of sensor data, and each channel is a thermocouple input. For accuracy, cold-junction compensation is supported by an onboard sensor that provides internal temperature measurement. Converted values resolve down to 0.1 °C/digit, making the device suitable for fine thermal control tasks. Data for all inputs appears in the controller image as 4 × 16-bit words, so scaling calculations remain consistent across platforms. No manual address wheels are required because slot position alone determines fieldbus mapping.
A typical station budget only allocates 75 mA of load to this unit, drawn from the Standard-Bus supply that powers all AKT terminals. Touch-safe design is shown by the IP20 protection class, and the assembly mass is only 75 g, easing strain on DIN-rail latches. Signal leads clip into push-in blocks and support direct thermocouple wiring without intermediate amplifiers in many applications. The terminal can be mounted horizontally or vertically, and wiring-fault indication reports open circuits to the PLC so control logic can respond to sensor interruptions.
