KL3312 | Bus Terminal, 2-channel analog input, temperature, thermocouple, 16В bit

The KL3312 analog input terminal allows thermocouples to be connected directly. The Bus TerminalвЂ™s circuitry can operate thermocouple sensors using the 2-wire technique. Linearization over the full temperature range is realized with the aid of a microprocessor. The temperature range can be selected freely. The error LEDs indicate a broken wire. Compensation for the cold junction is made through an internal temperature measurement at the terminals. The KL3312 can also be used for mV measurement.
