Nice video as always Pete. If you want to save yourself some cash for a 0-10V input. You can make a potential divider circuit putting a 5k potentiometer in series with a 6.8k resistor and coming off the middle to the analogue input. Feeding one side of the 6.8k resistor with the L+ terminal on the s7-1200, the other side goes to both the analogue input and the wiper of the pot, the other side of the pot goes to the M terminal on the s7-1200. I have actually built this in to a S7-1200 PLC trainer and it works a treat. I know you said you didn't have the skills or time, but this is pretty simple and will save you money should you want to utilise the other analogue input. Love all your PLC content. thanks from the UK.
Any PLC (or other similar instrument) that has a 0-5VDC or 0-10VDC analog input also basically has a 0-20mA or 4-20mA input capability. For example, if you were to connect a 250 Ohm resistor across that PLC's 0-10VDC input, and then also connect your 4-20mA current loop to those same terminals, your PLC would measure a voltage in the range 1-5V, which you can then scale as required using the match functions of the PLC.
Aww i thought it would actually generate the 0-10v 4-20mA signal by itself. No matter I will copy you pete and supply the 24v from the plc to the Droking. Still waiting for mine in Nigeria.

Here is the playlist for Siemens TIA Portal: ua-cam.com/play/PLyL0ResmI4Q3HIWvnMM18XpXkFMsS9Bcj.html The playlist should be in order. It starts with and/or, then 2/3 wire, then counters, and finally timers. Mixed in are some videos on Factory IO. Thanks for the comment Wade
Dear Sir, The disadvantage of the Drok Signal Generator device is that there maybe no power supply for it on the site. So, how can we use it? Do you suggest we should use a portable power supply source like batteries or something else? If yes, is there a specific Volt (VDC) and Amps (A) to use as a power supply for it?
It requires 24V DC which you can pick up off the PLC power supply. Out in the field though, you would be using a Process meter such as this one: www.itm.com/product/fluke-789-process-meter?gclid=Cj0KCQjwy8f6BRC7ARIsAPIXOjjmnz_pPN1kO-WdxuW7zVKxI1IA9M2sfV6lOf1pElvXcbWPpmC5SlsaApAgEALw_wcB

@@PeteVreeHi, I am not an engeneer but I am trying to make a device that is feed by: 1. In 110V 2. Out: 0-60V - 0-35mA. (with a knob to control the voltage and if is possible the mA as well. I want to use it as a intophoresis device. Can you help me out with the project? If there is a price, please let me know. Thanks.

Thank you. BTW anyone interested in some entertaining videos on aviation, etc. pls subscribe to youtuuba... he's got some great videos.
Great unit picked one up man great vid
Thanks Pete , very good tutorial .
These units are great! I have been using them for well over a year with my students. All the best. Pete

Very enjoyable videos, I think the playlist is not in order though. Is there an advise order to watch all the videos

Great video
you appear to be playing snap - some feat for a busy guy!
Is there similar product but with extra 24vdc output? If i want to test a Digital input foreaxample?

Hi, how do you change into mA, can I change it independently from the voltage? Thanks.

If we need passive current output what type connection require from generator
Waiting eagerly for your next video Sir.
I hopefully will have it done by next week... and you can call me Pete =)
Thank you Pete. Looking forward for it!
i will buy this one
in order to check amps, would you use the meter in series to measure?
Yup. You would connect in series with the meter in the dc amps setting.
Does it do 4 and 2 wire mA circuits?
