KL3228 | Bus Terminal, 8-channel analog input, temperature, RTD (Pt1000, Ni1000), 16 bit
The KL3228 analog input terminal enables connection of eight resistance sensors. The Bus Terminal’s circuitry can handle sensors using the 1-wire technique. 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 standard settings are: resolution 0.1 °C within the temperature range of Ni1000 sensors. The error LEDs indicate sensor faults (e.g. a broken wire).
