I/O Data Control

6.9.1 ANALOG OUTPUT SETUP

The 1020 provides current, voltage and pulse-rate analog outputs. Analog Output Setup allows you to
assign data functions for these signals. The flow computer's terminal strip contains the analog output
terminals.

Assigning Io Output Functions (see paragraph 6.10.6)
The Io analog output is a loop-powered (or externally powered), isolated 4-20mA DC signal that varies
linearly in relation to a selected data function.
To assign a function for the current output:
From [Analog Out Setup] menu cell, press the <Right Arrow> twice to access the [Io] option
list.
Move the cursor to the desired data function by pressing the <Up/Down Arrow>.
To store selection press <ENTER>.
