Thermostat is 2-channel temperature controller EEM based on MAXIM MAX1968 driver , capable of driving 6W into a TEC or resistive heater. Sensor interface is based on AD7172 ADC

Overview

  • Channel count: 2
  • Sensor: 10k NTC thermistor
  • Load (heater/TEC) drive: up to 8W (+-2A with 4V compliance)
  • Form factor: 3U module or stand-alone AL enclosure (Hammond 1455C1202).
  • Output connectors: Sensor and load connect via either terminal block connector on the front panel or via internal 100mil pin-header.
  • Programming interface: Ethernet accessible via RJ45 connector on the front panel
  • Power supply: +12V DC (1.5A max) supplied either by a front-panel barrel connector, via 100mils Zotino connector or PoE (up to 30W).
  • TM4C ARM Cortex M4F CPU

Comments

  • Idea is to make this board as advanced version of Thermostat_Thorlabs
  • 1 LED per channel to indicate if the temperature is in range . Also have a single power LED.
  • unique ID chip for TM4C and identification purposes.
