Introduction
Fig. 2: KL3311, KL3312 and KL3314
The KL331x analog input terminals allow the direct connection of thermocouples. The circuit of the Bus
Terminals can operate thermocouples using 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
indicates a broken wire. Compensation for the cold junction is made through an internal temperature
measurement at the terminals. mV measurement is also possible with the KL331x terminals.
KL3302 is no longer available and was replaced with KL3312.
