Introduction

The M-2004 is a digital temperature sensor module that provides four ports for 2- or 3 wire DS18B20 digital temperature sensor input. The DS18B20 temperature sensor has a high accuracy of ±0.5°C when measuring temperatures between -10 and + 85°C, with a total measurement range of between -55 and +125°C. Up to 20 DS18B20 sensors can be connected to each port on the M-2004 module in a daisy-chain arrangement with a maximum wiring distance of 100 meters. The M-2004 module is fully RoHS compliant, and features 4 kV ESD protection as well as 3000 VDC intra-module isolation.
