Process modules measure DC voltage or loop current and report and alarm on the data value, the rate of change for each channel, and the difference between adjacent channels.
The XM® 360 Process Modules are intelligent general-purpose monitors. They are complete process monitoring systems. These modules can collect trend data on events such as relay actuation. They can operate stand-alone or on DeviceNet™ networks to provide real-time data and status information to other XM modules, programmable controllers, distributed control systems, and condition monitoring systems.
