you need to use a Koyo DL06 or DL205 (with 260 CPU). Each has ASCII input instuctions. www.automationdirect.com Pete

Just installed a new pH controller. New controller has 4-20mA output for data recorder. Old recorder says input sensitivity equals 1mA. Do they mean the input is 0 - 1mA? If so are there any signal converters on the market to convert 4-20mA, or 0-20mA, to 0-1mA? P.S. The recorder is a...

you can wire them in SERIES but you'll have to recalibrate the first system when done.

I'm not too sure of your app. but look into Automation Dir's "DSData" Server.

You can't use a standard "straight" through cable.... They make a special cable for this purpose (I forget the name). Maybe someone else on this forum can tell you - but if you go to your local Radio Shack I'm sure they carry it... Good luck

I'm planning on converting a small office in my house into a large bathroom. I had an idea last night that seems pretty interesting to me. I would like to remove the ceiling (drywall and ceiling joists) finish the attic portion above the room and make it a vaulted ceiling. I know I'll probably...

How far can I reliably and accurately transmit a 4-20 mA Signal over a twisted pair shielded cable? I need to go about 150 ft. What AWG cable should I use? I'll be connecting a voltage/current meter with a 4-20mA output to a PLC. Thanks guys, Pete

THANK YOU SKILLS... Sorry it has taken me so long to reply but I live in the northeast and we just got hammered with 30 inches of snow... Anyway thanks for the info...I'll see what I can do with it. If you can help me a little more that would be great. This is what I have, and what I need...

Thanks Skills, The objective of the system is to measure the nickel concentration of a plating solution. The concentration of a nickel plating solution is measured in g/L, with 6 g/L considered a 100% concentration. The color of a 100% Nickel plating solution is a deep green and lightens...

I'm in the conception phase of a new project and wondering if I can use a PLC as the control device. I need to measure the opacity of a solution, most likely using a diode-receiver pair with a proportional voltage output. My question is how precise of a measurement can I obtain with a plc...
