The M2000 FlexIO is a general purpose HVAC controller whose inputs and outputs can be individually configured for use in various applications. Unlike most ProLon controllers, the FlexIO is not aimed at a specific HVAC sequence or piece of equipment, and instead can be used to perform any outlying functions that are not usually covered by existing ProLon devices.

The M2000 FlexIO Controller has 2 separate communication ports offering the same functionality on each. Both act as ports for incoming Modbus communications from other ProLon devices or interfaces, such as a Network Controller or remote computer with ProLon Focus software.
The example in Figure 3 shows the switches 1, 2 and 4 in the ON position. Therefore, the corresponding values are 1, 2 and 8, giving an address sum of 11. The ProLon network allows a maximum of 127 addresses; therefore 127 controllers. Figure 9 - Addressing Dipswitch...
Inputs The M2000 FlexIO controller’s inputs can be configured to accept a wide range of signal types. It is important to note that depending on the chosen signal type, a modification to the input jumper config- uration may be required (see p.7). Displayed below are examples of input wiring for most signal types.
Signal: Contact The M2000 FlexIO controller inputs can be used to monitor digital contacts. Please refer to Figure 11 to see how to correctly connect them. Internal Jumper: Thermistor Mode Contact Figure 11 - Connecting a dry contact to analog input 1 Signal: Voltage The M2000 FlexIO controller inputs can be used to monitor the voltage signal produced by a variety of transducers (such as pressure, gas, humidity and more).
Signal: Current The M2000 FlexIO controller inputs can be used to monitor the current signal produced by a variety of transducers (such as pressure, gas, humidity and more). Please refer to Figure 13 for correct wiring. It is important to ensure that the sensor shares the same common as the M2000 so that there is no 24 VAC feedback sent back to the controller, which can interfere with the controller’s ability to maintain accurate analog input readings.
The M2000 FlexIO controller contains 8 customizable outputs; five triac ON/OFF outputs (24VAC) and three analog outputs (0-10VDC). Output configuration is performed via the ProLon Focus software. An integrated resettable fuse protects each of the outputs of the M2000 against current surges and short circuits.
Typical Connection of Triac Outputs 1 to 5 On the M2000 FlexIO controller, all triac outputs produce a 24 VAC live voltage when activated. Note that all output voltages originate from the same voltage supply that is powering the controller (see Figure 16). Consequentially, only the live side of the output connections are usually needed;...
Figure 16 - Connecting the 24VAC power source Network Communication The ProLon M2000 FlexIO controller is designed to work standalone or networked with ProLon control- lers. When networked, it can receive the occupancy status, outside air and supply air temperatures in real-time.
