Analog output

Analog output can only process values between 0 and 1000.

Connect an Analog amplifier in front of the analog output to

con

vert 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 conver

ted 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 belo

w 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

nalog 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:
