FAST Opto Switch Board (Retired)

Product Number: FP-AUX-008-1

The FAST Opto Switch Board provides an elegant way to integrate up to 8 opto switches with a FAST I/O board. This board sits between a standard 8-switch input header on a FAST I/O board to essentialy "convert" those inputs to opto inputs. This board provides a header to power the 8 IR emitters as well as a header for the 8 IR detectors.


It contains a header which plugs into the standard 8-switch header from a FAST I/O board (plus 12-volt power), and it has a header to power the 8 IR LEDs for the opto senders, as well as 8 inputs for the opto receivers.
