Introduction

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.
