The MLIM-2 provides four channels dedicated as outputs. These channels can be
configured for functions such as alarming. The output is a current limited voltage
signal with the voltage/current characteristics shown in Figure 3... -24. As shown,
with a light load, the output voltage maintains approximately 4+ VDC but as the
current draw increases, current limiting occurs and the output voltage droops. The
output can be short circuited continuously without damage to the output drive
circuitry, but the OMP-MODL battery life will be drastically reduced.
Note
that the when the Output is OFF, it is merely floating, ie it is not driven to a
ground (or shorted to ground) potential. This may be a consideration when driving
TTL or other type inputs. A pull-down resistor (eg 10K) can be added on the terminal
strip connections from the output to the common to provide a low resistance OFF
state if necessary. Keep in mind if a pull-down resistor is added, that this resistor will
consume power when the Output is ON.
