ABB TU810V1 Compact Module Termination Unit

Description

The ABB TU810V1 Compact Module Termination Unit (MTU) is a passive, space-saving component designed for ABB S800 I/O and 800xA control systems. It features 16 channels (2×8 signal terminals) with a 50V voltage rating, supporting connection of field wiring to I/O modules. Key technical specifications include a maximum 2A per channel current rating, 5A total maximum current, IP20 protection rating, and approximate weight of 0.2 kg; typical dimensions are 64 x 170 x 58.5 millimeters, with alternative sizing available. It accepts solid wire 0.2-4 square meters, stranded wire 0.2-2.5 square meters, or 24-12 AWG wiring, and offers 50V isolation voltage, 21mA input current, and 0-20mA output current.

Equipped with integrated ModuleBus, it distributes ModuleBus to connected I/O modules and subsequent MTUs, and generates correct addresses for I/O modules via signal shifting. Two mechanical keys enable flexible configuration for different I/O module types, with 36 total configuration combinations. It supports transmission and conversion of digital, analog, and pulse signal types, and includes communication interfaces such as Modbus, RS485, and RS232, compatible with protocols like Modbus RTU, Profibus DP, and Ethernet/IP. Designed for DIN rail installation, it operates in temperatures ranging from -40 degrees Celsius to 70 degrees Celsius, and is widely used in industrial automation applications including process control, discrete control, machinery manufacturing, and packaging systems.
