4.4.1
Digital Inputs DI-1 to DI-4
The Digital Inputs can be configured to detect high voltages (Active High) OR low voltages (Active Low).
Active High Input Configuration
When configured as an Active High Input, the input state is considered ON when it becomes high. The
voltage thresholds that trigger the change in the input state are as follows:
State Voltage
High >5.0V
Low <1.0V/Disconnected
Active Low Input Configuration
When configured as an Active Low Input, the input state is considered ON when it becomes low. The voltage
thresholds that trigger the change in input state are as follows:
4.4.2 Digital Outputs DO-1 & DO-2
The Digital Outputs will pull to Ground and sink a maximum current of 250 mA when activated.
The outputs have over-current trip protection and, if tripped, the output must be changed to OFF or have a
power cycle to reset the current trip.
State Voltage
High >0.5V
Low <0.2V/Disconnected
