Beckhoff Automation kl3204-0030

The KL3204-0030 analog input terminal enables four NTC resistance sensors to be connected directly. The Bus Terminal's circuitry can handle sensors using the 2-wire technique. Linearization over the full temperature range is realized with the aid of a microprocessor. The standard setting of the Bus Terminal is a resolution of 0.1°C in the temperature range of the NTC 10 kΩ sensors. The error LEDs indicate sensor faults (e.g. a broken wire). The KL3204-0030 combines four channels in a single housing.
