Analog output
Analog output can only process values between 0 and 1000.
Connect an Analog amplifier in front of the analog output to
convert the analog output of the special function within a
range between 0 and 1000.
The analog output range -5000 to 5000 of a special function
is converted to a range between 0 and 1000 in the block
diagram below.
When an analog signal out of the range between 0 to 1000
is inputted to an analog output:
The analog output module operates as below for the analog
signal out of the range between 0 to 1000.
•
When the type of analog outputs is set to 0-10V/0-20mA:
When internal values less than zero are inputted to the
analog output, the analog output module outputs 0V and
0mA.
When internal values more than 1000 are inputted to the
analog output, the analog output module outputs 10V and
20mA.
The relationship between the internal value Ax inputted to the analog output and
the analog output value:
