Digital Inputs (DI)
Netbiter EasyConnect EC350 features 2 digital inputs of the dry contact type, i.e. they do not require
any control voltage, and will function with a switch or breaker. Please observe the following for the dig-
ital inputs:
• Max recommended cable length = 3m. It may be possible to use the inputs with longer cable
lengths, but this may give rise to problems.
•
Do not apply a power source to the digital input, as there is a risk it will burn out.
Relay Output (Digital Output)
There is one relay output with a rated load of 1A at 24V DC.
The relay output must be supplied from an isolating transformer using a secondary listed fuse rated at
maximum 3.3A and minimum 30V DC.
