NX-DA2203 need additional power supply unit?

4 posts in this topic

I'm not really familiar with Omron PLC's, but i was looking thru the data sheet for the NX-DA2203 and it says it gets its power from the NX bus. but the wiring example at the bottom shows that an additional power supply is needed? do i have to use the additional power supply unit' or is it powered from the PLC bus?

website: Omron NX-DA2203

data sheet: http://www.ia.omron.com/data_pdf/cat/nx-ad_da_ds_e_3_2_csm1057422.pdf?id=3187

The NX-EIC and NX-ECC couplers provide this power across the bus, it wires into the coupler itself.  The NX102 and NX1P2 do not, so a power supply module would be required.

great info, thanks! any idea where this is documented in the Omron literature?

 

i got their current PLC layout and there's already a power module on it so i think i will be ok to add these 2 more slices

 

(current PLC layout)

NX1P2-9024-DT1

NX-PF0730

NX-AD2603

NX-EC0142

(adding these 2 slices)

NX-DA2203

NX-EC0112

The manual for the PLC mentions it under expansion options, not sure of the page.

The manuals for the NX modules indicate which ones do or do not need a power supply...
