over-current events. The output is capable of switching coils and is therefore able to drive external relays
and low power solenoids. The open circuit voltage applied to the output should not exceed system
voltage or 72V.
As an alternate function, where additional inputs are required, the output can be configured as an analog
or digital input.
Note There is a limit to the amount of energy that the protection circuit can absorb. For instance, shorting
the output to power at 72V when the output is on will likely destroy the output.
The output is typically used to indicate warning and alarm conditions currently active and can be set to
active in the event of a measurement returning an exception. When configured to do so, the buzzer or
indicator lamp shown in the diagram below will turn on when a warning or alarm condition exists as pin
10 is switched to ground.
Figure 6.12. Using the output to drive a buzzer with permanent power
In solar or battery operated systems where permanent power is not available, externally powered current
output sensors can utilise the ORB switched power source on pin 3 as shown below.
