KL3208-0010 | Bus Terminal, 8-channel analog input, temperature, RTD (Pt1000, NTC), 16 bit
The KL3208-0010 analog input terminal enables connection of eight resistance sensors. The Bus Terminal’s circuitry can handle sensors using the 2-wire technology. Linearization over the full temperature range is realized with the aid of a microprocessor. The temperature range can be selected freely. The Bus Terminal’s default settings are: resolution 0.01°C within the temperature range of Pt/Ni1000 sensors. The error LEDs indicate sensor faults (e.g. a broken wire).
The HD Bus Terminals (High Density) with increased packing density feature 16 connection points in the housing of a 12 mm terminal block.
