The ECL-600 Series are microprocessor-based programmable controllers designed to control various building automation applications such as air handling units, chillers, boilers, pumps, cooling towers, and central plant applications. This series supports up to two ECx modules. These are I/O extension modules that operate off of a separate sub-bus, giving this controller a total of up to 40 universal inputs and 36 universal outputs.
This series contains two models as follows: ECL-600 and ECL-610. The ECL-600 series support various input types including resistance, voltage, and digital-based ones. Moreover, it provides digital, floating, pulse width modulation, and proportional control outputs for valves, pumps, heating elements, fan, and lighting applications. In particular, the ECL-610 has the added convenience of supervised Hand-Off-Auto (HOA) switches and potentiometers for manual override of an output.
The ECL-650 includes live graphics color display (integrated LCD operator interface).
