Table 4 Suggested resistor networks
The inputs also use a .01 uF capacitor and a 2.2K ohm resistor across
the LED in order to debounce switch and relay contacts. The inputs
are designed for input frequencies from 0 to 4KHz.

Example

The following statement is an example of how to read an input on the
5624:
A = INP(&H100)
B = INP (&H104)

Outputs

The 5624 provides eight isolated solid–state relays for outputs. The
outputs may switch both AC and DC loads. The loads may be
connected to either the OUT+ or the OUT– terminal. The DC load
voltage may be connected in either polarity. The rated load for an
output is 200 mA at 50V. This applies to both AC and DC loads.
Example
Writing a logic one to the output causes the output switch to close.
Writing a logic zero to the output causes the switch to open. The
following statement is an example of how to write an output for the
5624:
OUT &H100 + 8, &H01

Access LED

The amber LED will light briefly whenever the card is accessed(input
or output.)
