TB820V2 ABB I/O electronic frame base plate AC 800M S800 I O

TB820V2 ABB I/O electronic frame base plate AC 800M S800 I O

Product Overview

The ABB TB820V2 is a standard 8-slot I/O electronic frame (also known as the base plate or back plate) for the S800 I/O system, specifically designed for vertical installation. It is used to support and connect up to 8 S800 series I/O modules (such as DI801, DO810, AI810, AO810, etc.). It provides power distribution and high-speed data communication channels for the module through the built-in ModuleBus bus, and connects to the CI801 (electrical) or CI854A (optical fiber) communication interface module via a dedicated interface, thereby accessing the AC 800M controller.

Core features

8-slot standard design
Up to 8 S800 I/O modules (width ≤ 360mm) can be installed.
Support hybrid configuration (free combination of DI/DO/AI/AO)
Module hot-swapping support (software enablement required)
Integrated power distribution
Obtain + 5V and ± 15V logic power supplies from the system through the CI module
Provide stable power supply for all I/O modules without the need for additional power modules
Vertical installation structure
It saves the horizontal space of the cabinet and is suitable for compact control cabinets
The modules are stacked vertically, which is conducive to natural convection heat dissipation

Technical parameters

Small and medium-sized DCS sites: boiler auxiliary machines, pump stations, fan control cabinets
OEM machinery and equipment: Local I/O stations for packaging machines, filling lines, and material sorting systems
Water and sewage treatment plants: Signal acquisition and control in dosing rooms, filter tanks, and sludge dewatering rooms
Energy management system: Substation auxiliary signals, diesel generator monitoring
Renovation project: Replace the old PLC I/O and expand the control points by utilizing the existing AC 800M architecture

Installation and Usage instructions
Hardware installation
Fix the TB820V2 on the DIN rail;
Install the CI801 (electrical) or CI854A (optical fiber) communication module in the leftmost slot.
Insert up to 8 S800 I/O modules (such as DI801, DO810, etc.) in sequence on the right side.
Connect the CI module to the AC 800M controller using the ModuleBus cable.
Software configuration
Create an I/O station in Control Builder M and select the TB820V2 base plate type;
The software automatically identifies the model of the inserted module and the number of channels.
Assign a label to each channel (such as "Pump_Start_FB");
Download the configuration to the controller, and the system will automatically activate the I/O station.
Debugging and verification
A constantly lit RUN light in the CI module indicates normal communication.
The status of the I/O module can be monitored in real time through software.
Supports online forced input/output for convenient loop testing.
