The ABB 88UM01A BAUGRUPPEN is part of ABB's S800 I/O series and refers to an I/O Group Module or Group Module used in industrial systems. 

Model: 88UM01A

Series: S800 I/O

The 88UM01A module is designed to manage a specific group of I/O modules within the ABB S800 I/O system. It organizes I/O devices into a logical grouping, facilitating data communication between the field devices (sensors, actuators, etc.) and the control system. This module plays a key role in modularizing the control system and ensuring efficient data routing and communication.

The 88UM01A is a Group Module in the ABB S800 I/O series, designed to interface with other I/O modules in the system.

The 88UM01A module manages data communication between I/O modules and the system controller. It facilitates the exchange of data between connected input and output modules and ensures that control signals are transmitted effectively.

The 88UM01A module connects to the S800 I/O bus, which is part of ABB’s modular and distributed control architecture. 

It supports high-speed data transfer between I/O modules and the central control unit, typically within a 10 Mbps to 100 Mbps range.

The 88UM01A module typically operates on 24 V DC.

Power consumption:2 W to 4 W.

Operating Temperature: -20°C to +60°C

Storage Temperature: -40°C to +85°C.

Humidity: 5% to 95% relative humidity (non-condensing).

Like other modules in the S800 I/O series, the 88UM01A module has a compact design and typically has dimensions around 120mm x 80mm x 50mm.

It is designed to be mounted within an S800 I/O rack alongside other I/O modules, and can accommodate multiple I/O devices in a single system configuration.
