1761-NET-AIC 0.350 0
(1) Power supply loading for Series D and later modules.
(2) When using the BAS or KE modules to supply power to an AIC draws its power through the module. Add 0.085A
(the current loading for the AIC) to the BAS or KE module’s power supply loading value at 24V dc.
(3) The 24V dc loading values of the HHT, PIC, and DTAM are included in the 24V dc loading value of the processor.
(4) Current for the 1761-NET-AIC may be supplied from the controller communications port or from an external 24V dc source.
No current is consumed from the controller when an external source is used.
NA = not applicable
Watts per point — the heat dissipation that can occur in each field wiring point when energized at nominal voltage.
Minimum watts — the amount of heat dissipation that can occur when there is no field power present.
Total watts — the watts per point plus the minimum watts (with all points energized).
