Help - Using 1771-OFE1

[christiansjp]

Hello ererybody!

I have a great doubt,
have a plc 5/20 with a module 1771-OFE1(0-10 V) and can not increase the size of the chassis.
Can I use one output to two devices?

Any help would be great.

the two devices should work with the same level of control voltage input.

i think is it should help

Yes, you can wire the Voltage output of a 1771-OFE1 to more than one device. They will need to be, as you said, the same signal range. Wire them in Parallel, not Series.

You must be aware they will both receive the same signal voltage?

yes, i am aware. I just do not know if the module 1771 can support two devices on the same output.

thank you.

Yes, voltage signals are necessarily driven into high impedance loads, and paralleling them is OK (up to a limit of course). You will have no problems with two devices.
