General Information PL-C1050 Water Loop Controller Description The PL-C1050 Water Loop controller is designed to control a water loop system comprised of a boiler and a water tower with an internal pump. The built-in microprocessor offers precise digital control to maximize performance. The available control sequences are fully configurable, either locally or remotely with free software.

The example on Figure 3 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 Water Loop 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.
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.
Auxiliary Digital Input The C1050 Water Loop controller has a digital input that used for visualisation purposes only. It can detect an open or closed contact. The status of the input does not affect the sequence in any way. 24VAC Contact Figure 7 - Connecting the Auxiliary Digital Input REV.
The C1050 Water Loop controller contains 5 configurable outputs. The first 4 outputs are ON-OFF triac outputs. Output 5 is an analog 0-10VDC ON-OFF or modulating output, fully customizable 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.
2) Switch position to obtain a SINK passive output. Switch for Output 4 Isolated dry contact (On/O ) Figure 9 - Output in SINK mode Typical Connection of Digital Outputs 1 to 4 Two types of configurations are possible: 1) Active output (SOURCE). The C1050 is actively powering the load. External Load Figure 10 - Connection of Active Outputs 3 and 4 2) Passive output (SINK).
Typical Connection of Analog Output 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 12 - 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 (see Figure 14). The common for all inputs and outputs are the same as the power source’s common (exception: when an output is set to passive, the common for this output will not correspond to the power source common).
