Figure 9 – Analog Output Linear Scaling PV to FV
The 12IN-8SOUT-CO controller allows for the PV input to be selected from the list of the logical
function blocks supported by the controller. As a result, any output from one function block can be
selected as the control source for another. Keep in mind that not all options make sense in all cases,
but the complete list of control sources is shown in Table 23. By default, analog outputs are setup to
respond to the corresponding CANopen RPDO message.
There are three inputs to the output function block, each one with a unique source and number
object. For the control function (PV axis in Figure 9) objects 2340h
AO Control Input Source
and
2341h
AO Control Input Number
are used. For the enable function, objects 2350h
AO Enable
Input Source
and 2351h
AO Enable Input Number
are used. Lastly, for the override function,
objects 2360h
AO Override Input Source
and 2361h
AO Override Input Number
are used.
The output can be set to a custom FV value when output is disabled, either by Enable source being
zero or module state being not Operational, using object 2353h
AO Disable Drive FV
.

Relay Output
The controller has one Relay output. The Relay is driven by the CPU. The Normally Closed, Normally
Open and COMmon pins of the relay are available in the 8 pin Deutsch connector.
The Relay is capable of handling 5A/250VAC.
