Figure 24. Measuring a voltage
A channel configured as Disabled (Input) can measure external
voltage signals as shown in Figure 25. The input voltage
source must have the same electrical ground as the Relay
Driver ground. This type of measurement is commonly referred
to as
single ended input
.
WARNING: Be sure the channel is configured as
Disabled (Input) before connecting an input voltage.
Damage to the Relay Driver may result!
CAUTION: The input voltage must be less than or
equal to the Relay Driver power voltage.
