Sensor IQ vs Echo Relay Panel

Just curious, what's the difference between an ERP and a Sensor IQ panel? (Other than the relays are built into the breaker in the Sensor IQ panel.)

  • This is a question that comes up a lot.

    The panels have a lot of features in common:

    Mains-feed for 120/208 or 120/240 V for the US market, can be fed directly into the input lugs or an optional main circuit breaker 

    20A relays to turn loads on/off

    Ability to pair a 0-10V control signal to each relay circuit

    There are a few areas where the panels differ:

    Power control method - IQ uses hydraulic breakers to turn power on/off, ERP has a dedicated breaker panel that feeds into stand-alone relays

    Circuit capacity - IQ can go up to 48 circuits in a panel, ERP can go up to 24

    Load characteristics - IQ offers intelligent breakers for 15A, 20A, 30A; with each option being available in 1-pole, 2-pole, or 3-pole configurations.  ERP offers 10A, 15A, and 20A breakers which can pair with 1-pole, 2-pole, and 3-pole relays

    Load diversity - In addition to relays, ERP has an option to swap out a relay module for a 300W phase dimmer.

    System isolation - IQ offers an option to have the ground isolated, this comes in really handy if you have any AV gear hooked up to one of the circuits

    Inrush tolerance - IQ offers exceptional inrush tolerance (2 - 3 times what ERP offers) for systems that have high inrush demands

    Special loads - ERP offers 15A or 20A 1-pole GFCI breakers for installations that need such considerations
