DIO-32B

The input impedance of each isolated input is approximately 560 ohms
(factory default). The opto-isolator requires approximately 3 mA to turn on.
The maximum input current is 60 mA. Two things to consider when selecting
the input resistor. The first is turn on voltage for the circuit to sense, and
second is the maximum input voltage. Maximum input voltage must not provide
too much power to the input resistor, and must also not overdrive the opto-
isolator input current specification. The following formulas apply:

Turn on current: 3 mA
Isolator diode drop: 1.1 V
Resistor power Max: .25 W

Turn on Voltage = diode drop + (turn on current) x ( resistance)
Or :

1.1 + (.003) x R

Maximum voltage = square root of (.25 (resistor value))

The following table shows four common input resistors and the ranges
associated with each .

The maximum input voltage can be increased by increasing the input resistor
accordingly. Because socketed DIP resistor networks are utilized, they can
easily be replaced with a different value. This can be done at the factory, if
necessary. The input circuits are not intended for monitoring 120 volt AC
circuits. In addition to being too high a voltage for the circuits, it is dangerous
to have that high a voltage on the card.
