Power Meter PM-2104-3 v6

Product Information

Power Meter PM-2104-3 v6 is designed by Intech 21, Inc. for the purpose of accurate metering of the electrical power, voltage, consumed energy, and demand in a two- or three-phase power distribution system.

The PM2104-3 (PM) is a multifunctional device featuring configurable electrical energy meter and two isolated input/output channels, a choice of temperature sensors, built-in radio communication interface, LCD display, and LED annunciators.

Each of two multipurpose I/O channels can be configured independently to perform one of the following functions:

  • Temperature Control Output. Thermostat Heater/Cooler, Day/Night Settings, Curtailment Program automatic control modes available. The Thermostat function can be disabled allowing remote Direct Control of the Output.
  • Pulse Counter Input. Counts pulses from external standard Gas, Water and similar meters with dry-contact or active outputs.
  • Pulse Output. A dry-contact with programmable pulses/kWh rate.
  • Channel Not Used

Up to two external temperature sensors can be connected to the PM. The temperature sensors can be used for automatic Thermostat operations and/or supplying information to a Building Monitoring and Control System for more efficient heating/cooling control.

Embedded Radio Communication Device is configured as a Wireless Network Node, allowing the Power Meter to participate in the Intech21 Wireless Control Network.

The Wireless Control Network is designed to simplify deployment and reduce the cost of installation of the Building Monitoring and Control System.
