This COMMANDER I/O function card interfaces 8 digital input signals to a companion Base/Expansion cardfile assembly.
These inputs will process pulsing signals provided their frequency and associated debounce times are compatible (ie 40Hz @ 10msec debounce). Applicable status points will have an associated 16-bit register for holding the count values.
Operating environment (electronics)
COMMON INPUT VALUES
Higher voltage levels may be found for indication signals. This is accommodated by adding an external voltage dropping resistor in series with the plus terminal of the card. The nominal resistor values for various voltage levels are:
SIGNAL R-VAL ADD'L. SPECS 48VDC 6.8K CC 5% 1/4W 125VDC 22K CC 5% 1W
Use of the Universal Termination Assembly, or equivalent, is recommended when status signals exceed 48V.
