1794-OW8 Flex IO

[karivelm]

Hello,

I am using a 1794-OW8 module FLEX output card. From the card I am providing Voltage to the outputs does that mean that I must bring the desired voltage on A-00 & A01 terminals. Or does the voltage that I want to apply to my outputs come from B-17 (V-) & C-35 (V+)???

Best regards

A-00 and A-01 to power your output load.
B-17 and C-35 to power the module
Terminal no. depends on base used

Bring 24Vdc to A0 then jump to A2,A4,A6,A8,A10,A12,A12,A14

Bring 24Vcom to A1 then jump to A3,A5,A7,A9,A11,A13,A15.

Is this correct ???



No connect your +24VDC to even number "A0,2,4..." terminals. Connect your load to the odd numbered terminals "A1,3,5,..."

Connect your loads common to the -24VDC.

If loads are inductive install surge protection ( Free Wheeling diode will work well for DC power)

I would also fuse each load so no one device will take your whole system out.
