Easily expand the ezeio Controller with additional inputs and outputs using this wireless expansion module. Each input can be configured for 0-10V, 0-5V, 0-30mA, resistance/switched or pulse. In addition to the four inputs, there are also two relay outputs and an option to add a built-in temperature/RH sensor.
This wireless module is ideal for monitoring free-standing refrigeration units, hard to reach flow sensors or energy meters. An optional integrated Temp/RH sensor can be used to calculate dew point for anti-sweat heat control or air enthalpy for HVAC economizers.
When used in pulse mode, each input has a non-volatile 32-bit counter, and the device will also measure the time between pulses up to 65s with ms resolution.
