ABB TU811V1 module

ABB TU811V1 module

The TU811V1 is an 8-channel 250V compact modular terminal unit (MTU) in ABB’s S800 I/O system.

Basic information
Part number: 3BSE013231R1.
Type: Compact.
Connection mode: Terminal block connection.
Number of channels: 8 channels.
Voltage: 250V.
Functional characteristics
Field wiring connection: As a passive unit, it is used to connect the field wiring to the I/O module to realize the connection between the field device and the system, and also includes part of the module bus.
Module bus assignment: The module bus is assigned to the I/O module and the next MTU module, and the correct address of the I/O module is generated by transferring the output position signal to the next MTU.
Mechanical key configuration: Two mechanical keys are used to configure MTU for different types of I/O modules, each key has six positions, a total of 36 different configurations, to prevent the insertion of the wrong I/O module.

Electrical parameter
Maximum current: 3A per I/O channel.
Dielectric test voltage: 2000V AC.
Acceptable wire sizes: Solid wire 0.2-4mm ², twisted wire 0.2-2.5 mm² (24-12AWG).
Recommended torque: 0.5-0.6N ·m.
Peel length: 7mm.
Compatibility with I/O modules: Can be used with DI820, DI821, DO820, DO821 and other I/O modules.

Environmental parameter
Operating temperature: 0°C to + 55°C, the approved operating temperature range is + 5°C to + 55°C.
Storage temperature: -40°C to + 70°C.
Relative humidity: 5% to 95%, no condensation.
Protection class: IP20, according to IEC 60529.
