FX-7 inputs

[cleancondenser]

I do not have the docs at hand.
Can an FX-7 handle 4 to 20 ma. inputs? I have two 4 to 20 ma. Meters.
If not I will have to go upto
an FX-14

The inputs can do ...

− A99 temperature
− Ni 1000 (Johnson Controls) temperature
− Pt 1000 temperature
− NTC 10k temperature
− Ratiometric (0.5-4.5 VDC)
− 0-10 VDC

Run a 4-20mA signal through a 500 ohm resistor to get 2-10Vdc. The FX-07 will handle the 2-10 without issue.

Attached pdf is for an NDIO module but the wiring is the same. As long as your 4-20mA is externally powered from the "Meters" then it's only a 2 wire connection with the resistor. If the FX-07 is the source for the "Loop Power" you have to make sure that the "Meters" will accept a 15VDC power source.

You can find the specific wiring detail here.. http://cgproducts.johnsoncontrols.com/default.aspx?main.aspx&2

Good luck.
