S800 module for ICP Accelerometer
I am working on a project where we will be using triaxial ICP accelerometers. These accelerometers are connected with 4 cores, one for each axis and one for ground. Looking at the manual it looks like the power and signal cable connections don't really fit any S800 AI module although they look a bit close to an AI810.
Does anyone have any experience in conencting something like this to an 800xA system?

Hi Robert,
Unfortunately doesn't exist any S800 modules to read ICP signals and even you use 4-20mA accelerometers, the AI cards aren't fast enough to read something useful. In our projects we use online vibration systems connected with 800xA to interact with operation and superior level systems.

Hi,
The accelerometer probe output itself is usually a voltage derived from a constant current source applied to the probe and is not directly compatible with a simple 4-20mA input module.
There are numerous converters available that will provide the probe power supply and an isolated 4-20mA output that should be compatible with the AI810. Note that the frequency response of the AI module will be a limiting factor and you will get an average acceleration figure, which may or may not be suitable for your application.
ABB also has a multichannel channel condition monitoring module called the MCM800 that can accept probes directly or via 4-20mA inputs. It has Profibus and modbus connectivity to a controller and also has an ethernet interface for detailed signal analysis and diagnostics with seperate analysis software
