The ABB TU811V1 (3BSE013231R1) is a compact Module Termination Unit (MTU) designed specifically for ABB’s S800 I/O system, a flexible, modular process I/O solution widely used in industrial automation and control systems. This MTU provides 8 isolated channels for field signal connections with a rated voltage capability of up to 250 V, making it suitable for a variety of industrial input and output applications.
Primarily serving as a passive connection point, the TU811V1 facilitates the reliable interface of field wiring to the S800 I/O modules. It distributes the communication signals known as ModuleBus between the I/O modules and subsequent MTUs, also generating accurate addressing signals to ensure proper identification and operation of connected I/O modules. The module features mechanical keys configurable for 36 different module configurations, which help prevent incorrect module insertion during installation or maintenance.
The TU811V1 supports a maximum current per I/O channel of 3 A, with wire compatibility for solid conductors ranging from 0.2–4 mm² and stranded conductors from 0.2–2.5 mm² (24 to 12 AWG). It includes a latching device for secure DIN rail mounting that provides grounding for enhanced safety. This termination unit is designed to operate in typical industrial environments, with an operating temperature range of 0 to +55°C, protection class IP20, and compliance with key international standards including CE, UL 61010-1, and marine certifications (ABS, BV, DNV-GL, LR).
