LonPoint Hardware Guide 3-11
Tables 3.4 and 3.5 present the wire gauge that should be used in order to deliver the
specified power (total VA) across the distance shown. These tables only include wire
gauges from 24AWG (0.5mm) to 12AWG (2mm) as these are the wire gauges
supported by the Base Plate screw terminals. For the supply cabling use at least
24AWG/0.5mm, 90° C rated wire.
To determine the total power that a power cable must carry, total the VA
requirements for all of the devices that will be drawing power from that cable,
including both LonPoint modules and other devices. The VA ratings for the
LonPoint Modules are shown in the module data sheets and are summarized in the
following table.
Table 3.3 VA Ratings for LonPoint Modules
LonPoint Module VA Rating
DI-10 2.2VA
DO-10 6.5VA
DIO-10 4.75VA
AI-10 (all modes except 2-wire mode) 2.1VA
AI-10 (2-wire mode) 4.5VA
AO-10 4.5VA
SCH-10 2.4VA
LPR 2.0VA
To determine what gauge cable (in AWG or metric) will be required based on the total distance of
the power cabling, refer to table 3.4 for cabling measured in AWG and table 3.4 for cabling
measured in mm. If the wire gauge used is smaller than required, improper operation of one of
more modules will result. All data in tables 3.4 and 3.5 assume an average wire temperature of
+55°C.
