User Manual

The SIM-ALP2 can simulate a 2 wire 4-20 mA loop powered device, a 4 wire 4-20mA current source without an external power supply, or a 0-10VDC signal without an external power supply.

Simulating is easy in 1 mA/V or 0.1 mA/V increments by simply clicking the up and down buttons.  Each point can be individually calibrated to suit your needs.

With a range of 0-22mA and -10VDC to +10VDC, it can also simulate over and under range conditions.

Comes with carrying case and alligator leads.

Great value when you don't need an expensive calibrator such as a Fluke 707.

    Loop Simulator - Amazing!

    Posted by Nigel Novak on Oct 5th 2021

    Only 11 days to get to Western Australia from TW Controls in USA.
    The product is well constructed and Tim's operations video is so worthwhile watching.
    The Loop Simulator has a few surprising functional tricks. Amazing bit of kit...

    Analog Simulator and Generator

    Posted by Michael G on Jun 23rd 2020

    This is one of the best tools out there. I had got one a few years back and lost it. I had to have another one. Small enough to fit in your palm. I work in the industrial HVAC industry and this is one of the most helpful troubleshooting tools I have ever had the pleasure of owning. Accurate enough for calibrating controls to get you by in a pinch until you can get a higher end tool. Affordable enough to buy out of your own pocket if your work won't approve an expensive unit. 5 starts I'm my book!

    Great Analog Simulator at a reasonable price!!!

    Posted by Troy Porter on Oct 30th 2019

    Compact analog simulator that works great to source and simulate 4-20mA signals. This is a must have for troubleshooting analog inputs and cable runs! It also comes with a nice storage case. Highly recommended!!!
