IDEC SmartRelay Manual 187
• When the type of analog outputs is set to 4-20mA:
When internal values less than zero are inputted to the
analog outpu
t, the analog output module outputs current
values less than 4mA.
When internal values more than 1000 are inputted to the
an
alog outpu
t, the analog output module outputs 20mA.
The relationship between the internal value Ax inputted to the analog output and
the analog output value:
Note
Using an Analog trigger, you can determine that the internal values
less than zero or more than 1000 are inputted to the analog output.
When the type of analog outputs is set to 4-20mA, and
internal values less than zero are inputted to the analog
output, it outputs current values less than 4mA. You may
need to prevent the analog output module from outputting
current values less than 4mA. To do this, connect the Analog
Multiplexer (B007) in front of the analog output (AQ1) and
connect the Analog trigger (B006) in front of the Analog
Multiplexer to convert the internal values less than zero to
internal values equal to or more than zero.
