Hello guys, I would like to ask you for clarification regarding the connection between my accelerometer and the X20CM4800X module. The accelerometer cable I am currently using has only two wires: Red wire: connected to IEPE+ / signal Blue wire: connected to 0V Additionally, there is a grey shiel…

I would guess your sensor requires more current than the maximum of 5.5 mA :frowning:. You could contact the manufacturer to be sure.

Unfortunately, I have no knowledge of this type of measurement, but I’ll just try to understand the documentation. There is an internal circuit diagram for the module [image] According to Wikipedia this kind of sensors need a power supply, which this module can provide (but can be switched off …

This is the electrical data of my accelerometer. [image] my module provide 5mA/24VDC like a supply power. and the accelerometer had an excitation voltage between 18-28VDC, constant current excitation between 2 and 20mA. the probleme is that the module write that there is a Broken Wire and i don…

what voltage did you measure between A+ and A- input of the module by using a multimeter ?

I didn’t try to mesure it, but based on this circuit is 5 mA. [image]

[image] Yacine EL HAFIDY: I didn’t try to mesure it what is the problem ? the pins are accessible according to your photo above :slight_smile:

the problem is the module give me a broken wire True as you see in the photo. [image] this is the circuit, and i activated the channel and the IEPE supply but without ny result. [image] e LED always blink

i mesured the voltatge between IEPE +/- and i found it equal 3.18 V and this is less than 8 v rocommanded by B&R and for the sensor it works between 8 and 12V. i don’t know why the module give me this voltatge and how i could resolve this problem. [image]
