DO0 ... DO3: Relay outputs on the module
SEL: A logical 0 selects the 'Motor Current' input as source for AO+/AO-. A logical 1 selects the
'Analog Value' input as source for AO+/AO-. If the input is left open the 'Motor Current' is
automatically selected.
Motor Current: Usually this input is connected to the 'Motor Current' output of function block
'Current'. The input value is automatically scaled in a way that an input value of 200 (i.e. 200%
of I ) results in 100% at the analog output (e.g. 20mA or 10V). Input values > 200 are limited to
e
200.
Analog Value: A value of 0 ... 10000 results in 0 ... 100% at the analog output (e.g. 4 ... 20mA).
Use this output if you want to display an analog value on a pointer instrument or to send the
process value to a PLC.
Example: Display the motor current (0...800% of I
AnalogOut 0 Type
) on a pointer instrument of type 0...10V.
