Installation and Configuration
Connecting analog input signals
•
The STA-300 screw terminal panel supports both voltage and current loop inputs. You can
connect analog input voltage signals to the STA-300 in the following configurations:
•
Single-ended — Choose this configuration when you want to measure high-level signals,
when noise is not significant, when the source of the input is close to the STA-300 screw ter-
minal panel, and when all the input signals are referred to the same common ground. When
you choose the single-ended configuration, all 16 analog input channels are available.
•
Pseudo-Differential — Choose this configuration when noise or common-mode voltage
(the difference between the ground potentials of the signal source and the ground of the
STA-300 screw terminal panel or between the grounds of other signals) exists and the differ-
ential configuration is not suitable for your application. This option provides less noise rejec-
tion than the differential configuration; however, all 16 analog input channels are available.
•
Differential — Choose this configuration when you want to measure low-level signals (less
than 1V), when you are using an A/D converter with high resolution (> 12 bits), when noise
is a significant part of the signal, or when common-mode voltage exists. When you choose
the differential configuration, eight analog input channels are available.
NOTE
It is recommended that you connect all unused analog input channels to
analog ground.
This section describes how to connect single-ended, pseudo-differential, and differential voltage
inputs, as well as current loop inputs to the STA-300 screw terminal panel.
Connecting single-ended voltage inputs
shows how to connect single-ended voltage inputs (channels 0, 1, and 8, in this case)
to the STA-300 screw terminal panel.
