Description
1 24 VDC Power for Valves & Discrete Outputs
4 24 VDC Power for Inputs & Node Electronics
Discrete I/O Module(s) Power Jumper
All of Numatics, Inc., G2-2 I/O modules have a selectable power source jumper. This jumper determines
which Aux. Power connector pin will power these modules.
This option allows the user to select how each specific module will be powered during different conditions
(i.e. E-Stop). Each I/O module can be set-up independently allowing individual Output and/or Input
modules to remain active if needed.
Power Rating
Maximum system current capability is 8 amps. Care should be taken not to exceed 8 amp draw
through the 0VDC common pin (Current through all +24 VDC Pins combined).
Discrete I/O current draw is dependent on the device(s) connected. It is critical to know what these
values are in order to remain safely within the 8 amp limitation.
Loads should not draw more than 0.5 amps of current from any one individual discrete output point.

Recommended External Fuses:
External fuses should be chosen based upon the physical manifold configuration. Please refer to the next
page for the fuse sizing chart.
Power consumption for each Discrete I/O point is dependent on the
specific current draw of input sensor devices and output loads. Please
consult the factory for output current requirements greater than 0.5 amps.
