Purchase now the 2080-IQ4OV4, a high-efficiency combination I/O plug-in module designed to expand the discrete control capabilities of Allen-Bradley Micro800 controllers. This module is the ultimate space-saving solution for machine builders, providing a balanced mix of inputs and outputs in a single, compact slot.
What Is the 2080-IQ4OV4?
The 2080-IQ4OV4 is a versatile 8-point digital combination module that belongs to the Micro800 Plug-in family. It is compatible with Micro820, Micro830, Micro850, and Micro870 controllers. This module features four 12/24V DC digital inputs and four 12/24V DC sinking transistor outputs. By integrating both sensing and actuation points into one plug-in unit, it allows engineers to maximize the hardware utility of the controller without increasing the physical footprint on the DIN rail. The 2080-IQ4OV4 architecture is specifically optimized for small-scale automation tasks where space is at a premium but reliable digital control is required. It integrates seamlessly with the Connected Components Workbench (CCW) software environment for rapid configuration and deployment.

Industrial Architecture and Compatibility
The 2080-IQ4OV4 fits into any available plug-in slot on the front of the Micro800 chassis. Unlike sinking inputs, the «OV» outputs are sinking transistor types (NPN), which means the load is connected between the positive supply and the output terminal. This architecture is common in specific regions and specialized machinery where NPN logic is standard. The module provides a high level of flexibility for decentralized control, allowing the PLC to interface with high-speed sensors and small relays simultaneously. Within the CCW software, each point can be addressed individually, facilitating advanced ladder logic or function block programming for complex sequencing.
Expert Tips
When wiring the 2080-IQ4OV4, remember that since these are sinking outputs, you must connect the positive side of your load (solenoid, LED, or relay) to your 24V power source and the negative side to the module output terminal. To prevent electrical noise from interfering with the controller’s internal logic, always use shielded cables for longer runs. Additionally, verify that the total current draw of all four outputs does not exceed the module’s 2A limit, especially in high-temperature environments where thermal derating may occur.
Frequently Asked Questions
Q: Can the 2080-IQ4OV4 outputs be used for high-speed pulse applications?
A: No, these are standard discrete sinking outputs. For high-speed pulse-width modulation (PWM) or motion control, you must use the embedded outputs on the base Micro800 controller.
Q: What is the benefit of the sinking output type on this module?
A: Sinking (NPN) outputs are often required for compatibility with certain legacy sensors or specialized robotic controllers that utilize NPN logic standards.
