TB820V2 3BSE013208R1 ABB I/O module terminal base S800 I/O system Screw-type wiring

Product Overview

ABB TB820V2 is a standard I/O module Terminal Base specially designed for the S800 I/O series of ABB AC 800M control systems. This base adopts screw-type terminal blocks for installing compatible S800 compact I/O modules with a width of 22.5mm (such as AI801, DI801, DO801, etc.), providing a safe, clear and maintainable field signal access solution.

Core features

Compatible module types: Supports 22.5mm wide S800 compact I/O modules (such as AI801, DI801, DO801, AO801, etc.)
Wiring method: Screw-type terminal (Phoenix Contact type), supporting 0.2-2.5mm ² wires
Number of channels: Up to 8 on-site wiring channels (depending on the I/O module inserted)
Independent identification window: Each channel is equipped with a transparent label slot above it, supporting the insertion of paper or printed labels
Integrated shielding connection: Built-in metal shielding clamp, facilitating single-point grounding of the cable shielding layer and enhancing anti-interference capability
DIN rail mounting: Compliant with EN 60715 standard, directly clamped onto the TS-35 rail
Module lock design: Ensure that I/O modules are firmly inserted to prevent loosening

Technical parameters

Compact control cabinet: Deploy high-density I/O in PLC or RTU cabinets with limited space
OEM equipment integration: Provide standardized wiring interfaces for packaging machines, filling lines, test benches and other equipment
Remote I/O station (RI/O) : In conjunction with the BC810K remote communication module, a distributed acquisition system is constructed
Renovation and upgrade project: Replace traditional terminal blocks to achieve a modular and pluggable maintenance architecture

Installation and Usage instructions
Mechanical installation: Insert the TB820V2 into the standard 35mm DIN rail and lock it upon hearing a "click" sound.
Identification Settings: Insert printed or handwritten labels (high-temperature resistant label paper is recommended) into the transparent window above each channel.
Wiring steps
Remove about 8mm of the cable insulation layer.
Insert the wire into the corresponding terminal hole;
Tighten the screw with a screwdriver (recommended torque: 0.5 N·m);
Press the cable shielding layer into the top shielding clamp and fix it.
Module installation: Insert the S800 compact I/O module (such as DI801) vertically into the TB820V2 base and ensure it is fully in place.
Maintenance advantage: The I/O module supports hot-swappable replacement (subject to system configuration permission), without the need for power-off or rewiring.
