High density Output Module
This high density discrete output module has 16 channels that source 10 to 32 volts DC to the field devices.
The current rating for each output channel is 1 mA to 500 mA (0.5A). One screw terminal is provided for
the (+) user DC power source.
High Density Wiring Base
With the standard base, one screw terminal is provided for the output wire to each of the sixteen field
devices. One screw terminal is provided for the user DC power (+). Refer to the figure below for sample
wiring connections. Connect your output wires to terminals 1 through 16. Connect your DC (+) to terminal
18. You will need to externally distribute the DC power return to your field devices.
Watchdog Output Feature
The first DC output channel may be configured (using the Remote IO Toolkit program) as a watchdog
output. If this feature is selected, the output will be on when there is good command activity from the
gateway.
