4.10 Analogue outputs
In the standard version the PROBA110 has four analogue outputs. These analogue outputs can be for instance used to
control a recorder, proportional valves or electronic expansion valves.
The function and range of the analogue outputs can be programmed in the Internal Parameters.
As analogue output signal a 0/+10 Vdc voltage signal or 4/+20 mA current signal is available. Select the signals with
jumpers. See page 77.
4.10.1 P(I) outputs
The analogue outputs can be used for P(I) functions for cooling or heating. A proportional output usually gives a
slightly better control of the function.
See page 66.
4.11 Digital inputs
Next to the connection of the temperature sensors, the PROBA110 has six potential free digital inputs. The default functions
of these inputs are:
* Failure fan (IN 1)
* Failure cooling (IN 2)
* Failure heating (IN 3)
* Door contact (IN 4)
* External fatal alarm (IN 5)
* External non fatal alarm (IN 6)
The function of the digital inputs can be changed via the Internal Parameters.
4.12 Analogue inputs
Next to the connections for the gas and humidity sensor, the PROBA110 has a third analogue input. The function of this
analogue input can be programmed in the Internal Parameters.
A 12 - 17 Volt DC supply for the sensor is present.
4.13 Supply
The standard version of the PROBA110 uses a supply of 230/240 Volt AC (50 Hz). On request a 115 Volt AC (60 Hz)
version is available. This is connected to the relay board (terminals L and N ). It is absolutely essential that the protective
ground is also connected (terminal E ). The processor (the black box) is supplied from the relay board via the ribbon cable.
The clock inside the processor which keeps it alive in case the main supply is not present, is powered by a small battery. The
settings are kept in a non-volatile memory, which keeps its contents even without a supply.
