9500 Hardware Description
Inputs are 10VPeak inputs, with provision to read nominal TTL signals. Outputs are Nominal TTL voltage levels
and require external conditioning to drive high voltage and high current devices.
Output #1 to Output #8 HIGH voltage
Output "HIGH" (active):
· 2.5V minimum at 3mA source current
· 2.0V minimum at 32mA source current
Output #1 to Output #8 LOW voltage
Output "LOW" (inactive):
· 0.55V maximum at 64mA sink current
FET Output #7 and FET Output #8
The two FET Outputs allow driving high current SELV DC devices directly.
Output "HIGH" (active):
· Sink up to 1.5 amps to Logic Ground
Output "LOW" (inactive):
· Floating output
