Pin Type Signal Function Signal Level
1 A
RI
(Remote Inhibit)
1
Active-High input signal that is utilized to inhibit all power
module outputs (Pulled High internally). Low input (or
connection between Pins 1 & 9) will enable all outputs.
TTL
2 E DFI
(Discrete Fault Indicator) Active-High output signal that
indicates events/faults within system modules; derived from
open collector of floating opto-isolator. External pull-up
resistor required.
TTL
3 B PWR ON
Normally-open relay contacts that close when the ReFlex
