Allen Bradley 2080-SERIALISOL Micro800 Isolated Serial Port Plug-in Module

Product Overview

The Allen Bradley 2080-SERIALISOL functions as a high-performance serial communication expansion for the Micro800® controller family. This plug-in module adds an isolated RS-232 or RS-485 port to the controller without expanding its physical footprint. It provides critical electrical protection for the PLC when interfacing with long-distance field networks or third-party devices like VFDs and HMIs. We supply this unit as 100% brand new and original, ensuring full compatibility with your Micro820, Micro830, Micro850, or Micro870 systems.

Technical Specifications

The 2080-SERIALISOL utilizes a compact plug-in architecture to provide robust serial connectivity:

Engineering Advantages

• Superior Electrical Isolation: The 500V AC isolation barrier shields the Micro800 CPU from ground loops and transient voltage spikes often found in industrial serial networks. This protection prevents localized electrical noise from disrupting PLC logic execution or damaging internal circuitry.

• Dual-Standard Versatility: A single 2080-SERIALISOL module supports both RS-232 and RS-485 standards. This flexibility allows engineers to switch between point-to-point HMI connections and multi-drop Modbus RTU sensor networks without changing hardware.

• Zero-Footprint Expansion: The module seats directly into the plug-in slots on the front of the Micro800 controller. This design preserves valuable DIN rail space and allows for high-density I/O and communication configurations in small control cabinets.

• Simplified Modbus Integration: The module natively supports Modbus RTU and ASCII protocols. This enables direct communication with power meters, temperature controllers, and motor drives, eliminating the need for complex protocol converters or gateways.

• Secure Industrial Mounting: Unlike standard consumer-grade adapters, the 2080-SERIALISOL utilizes a screw-mounted interface. Tightening the mounting screws to 0.2 N·m ensures the module maintains constant electrical contact with the backplane even in high-vibration machinery environments.

FAQs

• How do I switch between RS-232 and RS-485 modes?

  The configuration occurs within the Connected Components Workbench™ (CCW) software. You select the desired standard and protocol (Modbus RTU or ASCII) in the plug-in module properties before downloading the project to the Micro800 controller.

• Is this a genuine, factory-sealed unit?

  Absolutely. We guarantee that every 2080-SERIALISOL we ship is 100% brand new in its original Allen Bradley packaging. It carries the verified UPC 885630058429 for industrial procurement traceability.

• What type of cable should I use for RS-485 multi-drop networks?

  Use a high-quality shielded twisted-pair cable. Connect the shield to a functional earth ground at one end of the network to minimize EMI, and ensure the terminal block connections follow the 0.22–0.25 N·m torque specification for long-term reliability.

• Can I use this module with a Micro810 controller?

  No. The Micro810 does not feature plug-in slots. The 2080-SERIALISOL is compatible with Micro820, Micro830, Micro850, and Micro870 controllers that support the 2080-series plug-in architecture.
