KL3204 | BECKHOFF Bus Terminal

Bus Terminal, 4-channel analog input, temperature, RTD (Pt100), 16 bitThe KL3204 analog input terminal allows resistance sensors to be connected directly. The Bus Terminal’s circuitry can operate the sensors using 2-wire connection techniques. Linearization over the full temperature range is realized with the aid of a microprocessor. The temperature range can be selected freely. The Bus Terminals standard settings are: resolution 0.1 °C in the temperature range of Pt100 sensors. The error LEDs indicate sensor faults (e.g. a broken wire). The KL3204 version combines four channels in one housing.Technical data KL3204Number of inputs 4Power supply via the K-busTechnology 2-wireSensor types Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni1000, resistance measurement (e.g. potentiometer, 10 Ω…1.2/5 kΩ)Connection method 2-wireMeasuring range -200…+850 °C (Pt sensors); -60…+250 °C (Ni sensors)Resolution 0.1 °C per digitConversion time ~ 250 msMeasuring current typ. 0.5 mA
