5.3.5. External Enable Input
The external enable is an opto-isolated input.
characteristics of this input.
To use an external power supply that is greater than 9 volts, a resistor must be added to
input feed. Place the resistor in series with each input to limit the current to a safe 20mA.
5.3.6. Fault Output
The BAS has a fault output that is opto-isolated. The electrical characteristics of this
output are shown in the Figure 5-7.
