Order now the 2080-OF2, a precision-engineered 2-channel analog output plug-in module designed to enhance the process control capabilities of Allen-Bradley Micro800 controllers. This module is the perfect solution for providing speed references to variable frequency drives or modulating control valves in a compact footprint.
What Is the 2080-OF2?
The 2080-OF2 is a non-isolated analog output module that plugs directly into the front of any Micro810, Micro820, Micro830, Micro850, or Micro870 PLC. It provides two channels of analog output, supporting both 0-10V voltage and 0-20mA current signals. The ability to generate accurate analog signals is essential for closed-loop process control, allowing the Micro800 to act as a PID controller for pressure, temperature, or flow applications. The module’s architecture is focused on cost-efficiency and modularity; by using a plug-in instead of a side-car expansion module, users save significant space on the DIN rail. Within the Connected Components Workbench (CCW) environment, the 2080-OF2 is easily scaled and configured, enabling rapid integration into existing industrial automation projects.

System Integration and Analog Performance
The 2080-OF2 uses high-quality digital-to-analog converters to ensure signal stability and repeatability. In a typical system architecture, the module receives digital values from the PLC processor and converts them into the physical signal required by field actuators. It is commonly used as a speed reference for PowerFlex drives via the 0-10V input or to control proportional pneumatic valves via 4-20mA. The plug-in design ensures that the I/O remains electrically close to the processor, minimizing the risk of signal degradation across long internal buses. Its 12-bit resolution provides a fine step size of approximately 2.44mV or 4.88µA, which is sufficient for most industrial modulation tasks.
Maintenance Tips
Because the 2080-OF2 is a non-isolated module, you must ensure that the analog field devices share a common ground reference with the PLC. Ground potential differences can cause significant measurement error or even damage the output circuitry. Always use shielded twisted-pair (STP) cabling for analog signals and ground the shield at the PLC chassis ground to mitigate electromagnetic interference (EMI). Periodically check the plug-in for secure seating in the controller slot, as high-vibration environments can occasionally cause plug-in modules to lose contact with the internal bus pins.
Frequently Asked Questions
Q: Does the 2080-OF2 support a 4-20mA output range?
A: Yes, it supports 0-20mA. You simply scale your 4-20mA requirement in the CCW software so that your minimum value corresponds to 4mA (819 counts at 12-bit resolution).
Q: Can I use one channel for voltage and the other for current?
A: Yes, each of the two channels on the 2080-OF2 is independently configurable for either voltage or current mode in the software configuration.
