ABB input and output module TP853 3BSE018126R1

The TP853 3BSE018126R1 is an I/O module for ABB’s System 800xA or AC800M series controllers, suitable for distributed control systems (DCS) or programmable logic controller (PLC) architectures. It is designed to provide a highly reliable and flexible signal interface for industrial process control, supporting analog, digital, or mixed signal processing.

Core Positioning

As an expansion module for ABB industrial automation systems (such as the AC800M controller and OmniCore robot controller), the TP853 3BSE018126R1 focuses on signal acquisition and control output, enabling data exchange between field devices and the control system.

Input Function

Acquires signals from field devices (such as sensors and transmitters) and converts them into digital or analog quantities that the controller can interpret.

Supports a variety of signal types (such as 4-20mA, 0-10V, RTDs/thermocouples, and digital inputs). Please refer to the technical manual for details. A-B MPAS-B80181-V05S2ALIN STG,CVR,Servo Motor

Output Function

Converts controller commands into executable signals for field devices (such as driving valves, motors, and indicator lights).

Output types may include relay contacts, transistor switches, and analog signals.

Communication and Diagnosis

Communicates with the main controller via a bus (such as Profibus, Modbus, or EtherCAT) to exchange data.

Equipped with self-diagnostic capabilities, it can detect channel faults, power supply anomalies, and report status via LED indicators or the network.

Core Functions

Analog Input (AI): Acquires continuously changing physical quantity signals (such as 4-20mA and 0-10V) such as temperature, pressure, and flow.

Analog Output (AO): Outputs continuous control signals to drive actuators such as control valves and frequency converters.

Digital Input (DI): Acquires discrete quantities (such as 24V DC high/low levels) such as switch status and button signals.

Digital Output (DO): Outputs switch control signals to drive devices such as relays and indicator lights. ABB UF C760 BE41 - 3BHE004573R1041 Industrial Control Board

High-speed counting and pulse output: Select models support high-frequency pulse signal processing, suitable for motion control scenarios.

Technical Features and Advantages

High Precision and Stability

Utilizing a 16-bit ADC/DAC chip, the analog signal resolution is high, meeting the needs of precision control.

Designed with industrial-grade components, it operates in a wide operating temperature range of -20°C to +70°C and is resistant to vibration, dust, and water (IP20 protection).

Flexible Configuration

Independent channel configuration: Each input/output channel can be individually configured for range and filtering parameters, accommodating diverse signal types.

Modular Expansion: Hot-swappable, it can be combined with other ABB I/O modules (such as digital modules and thermocouple modules) to expand system capacity.

Powerful Communication Capabilities

Supports mainstream industrial protocols such as Profibus-DP, Modbus TCP, and EtherNet/IP, enabling seamless integration into control systems such as ABB 800xA and Freelance.

Dual Ethernet ports support redundant communication, enhancing system reliability.

Diagnostic and Maintenance Functions

A built-in self-diagnostic program monitors channel status, communication failures, and other issues in real time, providing alarms through LED indicators or host software.

Supports remote firmware upgrades, reducing maintenance costs.

Typical Application Scenarios

Process Automation

Chemical Production: Collects reactor temperature and pressure signals to control valve openings to maintain stable process parameters.

Water Treatment Systems: Monitors liquid level and flow, and adjusts pump operating frequency for energy-saving control. Emerson 8920-PS-DC Power Supplies IS Module DC Power Supply (8 modules)
