The ABB 88VUO1E is a Coupling Module designed for use in ABB’s S800 I/O system. It is used to link I/O modules in distributed control systems (DCS) control systems, enabling communication between different parts of the control system. Coupling modules, like the 88VUO1E, are essential for ensuring that signals from input and output modules can be properly routed and managed within a larger system, typically supporting fieldbus communication.

Product Type: Coupling Module

Model: 88VUO1E

Series: S800 I/O 

Function: The 88VUO1E coupling module is designed to provide the electrical connection between the I/O modules and the communication network. It serves as the interface between digital or analog I/O modules and the control system, enabling data transfer and communication over the industrial network.

The 88VUO1E typically does not directly provide I/O channels; instead, it acts as a connector between I/O modules and the system network. It supports multiple I/O modules (both analog and digital) within a control rack, linking them to the communication system.

The coupling module supports S800 I/O Bus communication, which is part of ABB’s proprietary system for distributed control.

The module allows communication with ABB’s AC800M controller or other control systems by linking the I/O modules to the S800 I/O communication bus.

Supports high-speed data transmission for control signals and status updates between the I/O modules and the controller.

The data transfer rate：10 Mbps to 100 Mbps

The 88VUO1E coupling module typically operates on 24V DC power.

The power consumption of the module is relatively low, typically ranging between 2W and 4W depending on the setup and number of connected modules.

Operating Temperature: -20°C to +60°C.

Storage Temperature: -40°C to +85°C.

Humidity: 5% to 95%

The module has a standard size for ABB S800 I/O modules, which is typically 120mm x 80mm x 50mm.

The 88VUO1E module may support redundant communication setups for high reliability in critical applications.
