The C1050 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 example below shows the switches 1, 2 and 4 on the ON position. So the corresponding values are 1, 2 and 8, giving an address sum of 11. (1+2+8=11) The Prolon network allows a maximum of 127 addresses, therefore 127 controllers. Figure 3 - Addressing Dipswitches...
The C1050 FlexIO Controller has two 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.
Inputs Analog Input The C1050 series controllers are equipped with three general purpose analog inputs. These inputs can be configured to receive signals of the following types: • Thermistor (Ω) • 0-5V • 4 -20mA • 0-10V When a thermistor is used, the thermistor must be 10KΩ TYPE 3.
Signal: Contact The C1050 FlexIO controller inputs can be used to monitor digital contacts. Please refer to Figure 7 to see how to correctly connect them. Contact Figure 7 - Connecting a dry contact to analog input 1 Signal: Voltage The C1050 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 C1050 FlexIO controller inputs can be used to monitor the current signal produced by a variety of transducers (such as pressure, gas, humidity and more). The C1050 requires a 250 Ohm resistor in parallel with the COMMON. Please refer to Figure 10 for correct wiring.
The C1050 FlexIO controller contains 5 customizable outputs; four triac ON/OFF outputs (24VAC) and one analog output (0-10VDC). Output configuration is performed via the Prolon Focus software. An integrated resettable fuse protects each of the outputs of the C1050 against current surges and short circuits. This protection will cut the current to the output as soon as an overload condition is detected.

Typical Connection of Analog Outputs Two types of configuration are possible: 1) The C1050 powers the load and provides a control signal. 24 VAC power (From terminal block #2 of the controller) Controlled 0-10v Load Figure 14 - Connecting the analog output (controller powered) 2) The C1050 only provides the control signal to the load, which is powered by an external source.
Power Source The Prolon C1050 controller is powered by a 24 VAC power source connected using the "COM" terminal and the "24 VAC" terminal. The common for all inputs and outputs are the same as the power source’s common (exception: when an out- put is set to passive, the common for this output will not correspond to the power source common).
