Description
The KL3228 analog input terminal enables connection of eight resistance sensors. The Bus Terminal’s circuitry can handle sensors using the 1-wire technique. Linearisation over the full temperature range is realised 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).
