Description

ABB TU811V1 8-channel compact module terminal unit

Functional features: It is a passive unit used to connect the on-site wiring to the I/O module. It also includes part of the ModuleBus, which can be assigned to the I/O module and the next MTU, and generate the correct address for the I/O module by shifting the output position signal to the next MTU. There are two mechanical keys for configuring MTU to different types of I/O modules. Each key has six positions, with a total of 36 different configurations.

Electrical parameters
Rated voltage: 250V.
Number of channels: 8 channels.
Wire specifications: The specifications of solid wires and stranded wires are both 0.2-4mm².

Communication parameters: The communication interface is ModuleBus, which is used to communicate with I/O modules and other Mtos, and to achieve the allocation and address generation functions of ModuleBus.
Configuration parameters: There are two mechanical keys, each with six positions, totaling 36 different configurations, which are used to configure MTU as different types of I/O modules. However, this is only a mechanical configuration and does not affect the functionality of MTU or I/O modules.

Environmental parameters
Operating temperature: Generally 0℃ to + 55℃, certified for + 5℃ to + 55℃.
Storage temperature: -40℃ to + 70℃.
