FM33xx-B110-xxxx - Introduction

12 and 32 channel analog thermocouple input plug with open-circuit recognition (TC plug)

The FM33xx-B110-xxxx thermocouple input plugs allow thermocouples to be connected directly. The TC plug circuit 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 indicates a broken wire. Compensation for the cold junction is made through an internal temperature measurement at the terminals.
