quad inputs

Guys, I am running a micro1400 and I want to add two of these http://www.micronor.com/products/files/MR190/MDS_MR190.pdf into my system to give my customer control over pressure and position. is this possible with this PLC and if so how would I do it? as far as how to wire and programming thanks for the help JD

That particular device outputs pulses but does not give a zero reference, so don't expect the scale to mean anything at all. You will need a 12 VDC power supply to power up the Micronor device, and you will need a Micrologix 1400 that accepts DC inputs. You could possibly create the correct power supply with resistors but I recommend that you just buy two separate power supplies, a 12 VDC power supply for the Micronor device, and a 24 VDC power supply for the PLC. If you look carefully at the Micrologix 1400 specifications, an "on state" on the DC input can be anywhere between 4.5 VDC and 24 VDC. Use a pullup resistor as shown in the Micronor manual to generate the appropriate voltage pulses and wire them into a digital input that is connected to a high speed counter input. Use a high speed counter (HSC function file) for the input. Then the output pulse count will appear directly in the high speed counter function file.

Here the manual. page 101 show you how to use high speed counter. http://literature.rockwellautomation.com/i...rm001_-en-p.pdf
