UDAS-1001E Series Data Acquisition Systems
1-4
Digital Input/Output Digital Input/Output
•
16 Programmable digital I/O channels. Groups of 8 separately programmable for input or
output.
•
Digital inputs can be programmed to read digital signal status, detect a change-of-state or to
perform low speed event counting (up to 2 kHz).
•
Digital outputs can drive TTL level signals.
•
8 of the 16 I/O channels can be configured for preset direction and output state levels for safe
power-up and reset situations.
Counter Counter
One 16-bit counter channel performs general purpose event counting and frequency measurement
up to 20 MHz
up to 2
MHz for high-speed event counting.
Termination Termination
The UDAS-1001E-3 and UDAS-1001E-4 units have built-in depluggable termination blocks for
connecting I/O signals. The UDAS-1001E-1 and UDAS-1001E-2 units have a 50-pin I/O connector
for attaching external termination. Information on termination panels is provided in Appendix B,
Accessories.
