drive analog inpuTs
The GS4 has 3 analog inputs (AI1, AI2 and AI3) that can be configured for a variety of input
functions. AI1 and AI2 must be configured via a Parameter (P4.05 or P4.06). They also have a DIP
switch located above the I/O terminal strip that allows them to be configured as voltage or current
inputs. AI3 is voltage input only. All three inputs have a variety of settings in Parameter Group 4
(P4.xx) that allows you to customize their scaling, offset, etc.
•
AI1: 0~10V, 4~20 mA, 0~20 mA (See P4.05 and the DIP switch AI1 above the I/O terminals)
•
AI2: 0~10V, 4~20 mA, 0~20 mA (See P4.06 and the DIP switch AI2 above the I/O terminals)
•
AI3: 0~10V, -10V to +10V
Connecting the analog inputs to PLC outputs is very straightforward. All three analog inputs share
the same common.
NOTE: The GS4 analog inputs do not supply the current when configured for 0~20 mA or 4~20
mA. The analog output device needs to supply the loop power.

In this example, AI1 is configured for 0~10V (DIP switch and P4.05). AI2 is configured for 4~20 mA
(DIP switch and P4.06).
