This connects to the (rapidly evolving) Monitor-o-Matic 8000 software mentioned in a previous post.
This adaptor and software is going to be used this week during testing of a piece of industrial equipment. This test adaptor will be monitoring both 4-20mA and relay outputs (using the in built power supplies to generate the voltage on one pin of the relay contacts and the digital inputs to monitor the other pin).
Analog Discovery 2
The AD2 is a very versatile piece of kit with a good balance of analogue and digital input and output for a reasonable price. It includes
- 2 x 14-bit, 30MHz differential scope channels
- 2 x 14-bit, 10MHz waveform generators
- 16 x digital logic I/O with pattern generation and logic analyser
- 2 x programmable power supplies
We’re going to be monitoring how well this device performs for monitoring during testing. We may need to add extra filtering beyond that already fitted such as optical isolation for the digital inputs.
We may also look at fitting a battery and a USB to fibre optic converter for fully isolated measurements in a variety of EMC environments.
