Thermo Scientific 4-20mA ULT Connection Operating instructions

  • Hello! I've reviewed the instructions for the Thermo Scientific ULT product and its 4-20mA support. The document details the connection process using the provided terminal block and pin configuration to integrate with a Building Management System (BMS). It also specifies the parameters for the 4-20mA output, with 4mA corresponding to -115c and 20mA to +50c. I'm ready to address any questions you might have about this process.
  • What is the terminal block part number?
    What pins are used to connect to the facility BMS?
    What are the parameters for the 4-20mA output?
