The Allen Bradley Micro800 2080-IF4 module is a 4-channel, non-isolated, unipolar voltage/current, analog input plug-in module. As with all of the Bulletin 2080 plug-in modules, It can be plugged in the base unit of Micro820, Micro830 and Micro850 Controllers to extend its I/O functionality, without increasing the controller’s footprint (i.e no need for additional rack space).

Every channel on the Micro800 2080-IF4 can be configured for either unipolar (i.e positive only), current, or voltage input. This plug-in module is configured using the MS Windows based Connected Components Workbench™ software, which is also used to create and load the application program on the Micro800 Controllers. The configuration options available in the software for the Micro800 2080-IF4 include setting the sampling frequency (i.e how fast the measurement will be) for any individual channel to any of 50 Hz, 60 Hz, 250 Hz, 500 Hz values. Additionally, the user can choose either Voltage or Current inputs, or even disable a channel entirely.

Analog inputs of the Micro800 2080-IF4 can range from 0 to 10 Volts for voltage mode, and from 4 to 20 mA for current mode inputs, all at a 12-bit resolution, which means it can interpret measurements down to 2.44 mV for voltage, and .0049 mA for current. Analog inputs can be used to interface multiple types of sensors, devices and current-loop transmitters, which is a vital feature to receive the feedback signal in Closed Loop Control Systems (i. regulatory PID control systems), which are used in continuous process applications found in a number of industries (chemical, oil & gas, motion control, etc).

In addition, software-based high or low thresholds can be installed into Micro800 controllers that are enabled with a 2080-IF4 plug-in, in order to be able to monitor values for alarming and shut down purposes.

The ambient temperatures recommended for the Micro800 2080-IF4 operation are from -20 to 65 degrees Celsius (-4 to 149 degrees Fahrenheit).
