KL3214 | Bus Terminal, 4-channel analog input, temperature, RTD (Pt100), 16 bit, 3-wire connection
The KL3214 analog input terminal allows four resistance sensors to be connected directly. The Bus Terminal circuit can operate sensors using the 3-wire technology in a compact 12 mm housing. A microprocessor handles linearization across the whole temperature range, which is freely selectable. The Bus Terminal’s default settings are: resolution 0.1°C. Sensor malfunctions such as broken wires are indicated by error LEDs.
