1. 11 A millivolt is one thousandth of a volt.

2. Units with relays will operate millivolt systems, but often make an audible "click" noise when switching on or off.

3. Analog input modules amplify, isolate, filter, and multiplex input signals from thermocouples, strain gauges, RTDs, thermistors, millivolt sources, voltage sources up to 250 Vrms, and current sources.

4. The 5B family provides isolation, noise rejection, and amplification for millivolt sources, volt sources, 4-20 mA sources, 0-20 mA sources, RTDs, thermocouples, strain gauges, and frequency inputs.

7. Typically one or more regular batteries must be installed to operate it, although some so-called "power stealing" digital thermostats use the common 24 volt AC circuits as a power source, but will not operate on thermopile powered "millivolt" circuits used in some furnaces.
