The connection of the PT1000 temperature sensor to the AOR is illustrated on the following figure:
2.4.8.2
Voltage analog outputs – AOV
These analog outputs only allow output in the form of a voltage source, i.e. 0–10 V.
The values are of the WORD type in the range 0 to 4000. To write and read values, the values must first be
converted using linear interpolation (0 = 0 V; 4000 = 10 V).
The following figure illustrates the connection of the controlled device to the AOV:

Relay output connection – RO
The relay outputs are connected to the ROx or ROy.x and COM terminals and are used for switching two-
state elements with alternating or direct voltage. The COM terminal (can also be shared by two relays) is
used to supply the switching voltage to the given relays ROx or ROy.x. The relays are connected in the NO
(normally open) state, so in the off state the contacts are not connected.
Switching on of each output is signalled by lighting of the LED with the corresponding marking. Protection
against overload and short circuit is performed by external protection for each output separately. The rated
current and fuse type are selected according to the load and the nature of the load with respect to the
maximum output current.
