Digital Output

The digital output is used to drive solenoids, latches, valves, pumps, lamps, etc. In the OFF/OPEN state

digital outputs present a high impedance to the external equipment and prevent current from flowing.

The high impedance when OFF/OPEN should not energize common equipment. In the ON/CLOSED

state the digital output presents a low impedance to the external equipment and allows current to flow.

This energized the external equipment. In the event a dangerous condition is detected in the digital

output, like too much current, the digital output will enter protection and disable the output. The user

can choose whether the digital output should clear the ON/CLOSED command or to retry the command

when safe to do so. Users should always follow good grounding practices and connect one ground wire

for every digital output used.

• The digital output with 2 Amp switch to ground is implemented

Digital Output with 2 Amp V+ Switch to Ground

The digital output with 2 Amp switch to ground is implemented with a solid state NMOS transistor. The

impedance when OFF/OPEN is roughly 62 kiloOhms to ground. The impedance when ON/CLOSED is

roughly 50 milliOhms to ground. The current flowing through the equipment is measured and circuitry

protection turns on above 2 Amps.
