The xducer CAN take 24vdc, however, the analog input can only take 10vdc. The wiper resistance of the xducer is in series with the analog input resistance. The analog input resistance is around 200k. This means that the input is going to drop most of the 24vdc. As the xducer travels the wiper resistance of it approaches zero causing all the 24vdc to drop across the analog input. I had a low power zener so I used a voltage divider along with it and it appears to be working nicely.

I'll give it a try. Thanks.

I want to monitor a 1k linear xducer. I was going to use a voltage divider with resistors but the xducer across the load alters the thevenin's resistance. Will the diode prevent this?

I am wanting to experiment with the analog inputs of my ML 1100 but am having trouble finding a 10vdc power supply. Any suggestions?

I've done some basic hot links from a ML1100 to Excel over our network but have'nt used VB. What is a good source to learn VB. My other question (and I know it sounds silly) but where do you type in the VB code at for an Excel spread sheet. Thanks.

Go to Controller Properties under your Project tree and you'll find a tab labeled Passwords.

If I use a 1k resistor in series the max I get is 13.24ma. If I ever-so-reluctantly measure directly I get the full 20ma. My manual specifications does list an output protection of +/- 32ma and also has a continuous open and short-circuit protection so I guess I'm safe doing a direct measure. Thanks for all the input.

I'm using a 1762-OF4 analog output that I have configured for 4-20ma. Is there a way to measure the output without any load?

Northwest Indiana. I even checked on the AB website and a second local distributor.

Thanks for the replies guys. I've switched to a 4-20ma (no external 24VDC) to play it safe. Now I just have to wait on the Analog module. 20 day lead time! Give me a break.

Thanks Alaric. I'll look into that. I already have 8761(22 AWG). Can I get away with that? TWC, the valve is powered by the 0-10VDC.

I will be using a 1762-0F4 to drive a 0-10VDC pneumatic proportional valve. I would like to know if I will have proper signal strength if I am, let's say, around 100ft from module to valve?

I tried the first topic with N7:0,L24,C1 and the second topic with N7:120,L24,C1 but it didn't seem to like that either. I'll keep scratching. Thanks for your reply.

I am using the N7 file to store data in a ML 1100 and am sending to Excel. This seems to work fine until I try to link from N7:100 or more. When I do this my Excel cells display a "#N/A". If I am in my RSLinx Data Table Monitor and try to navigate to N7:100 or more the entire file will display "Error!" (with a yellow background) in each integer file. Is there a data limit for hot links?

I'm still experimenting with mine but I am able to force outputs via the ethernet port, upload/download and monitor the program.
