24 V Input
PRIMARY CONTROL - PC PIN
Module Enable/Disable
The module may be disabled by pulling PC to 0 V (2.3 V
max) with respect to the –Input. This may be done with an
open collector transistor, relay, or optocoupler. Converters
may be disabled with a single transistor or relay either directly
or via “OR’ing” diodes for 2 or more converters. See Figure 2.
Primary Auxiliary Supply
During normal operation only, the PC Pin can source 5.7 V @
1.5 mA. In the example shown in Figure 4, PC powers a mod-
ule enabled LED.
Module Alarm
The module contains “watchdog” circuitry which monitors
input voltage, operating temperature and internal operating
parameters. In the event that any of these parameters are
outside of their allowable operating range, the module will
shut down and PC will go low. PC will periodically go high
and the module will check to see if the fault (as an example,
Input Undervoltage) has cleared. If the fault has not been
cleared, PC will go low again and the cycle will restart. The
SC pin will go low in the event of a fault and return to its nor-
mal state after the fault has been cleared. See Figures 3 and 5.
