ABB TY801K01 3BSE023607R1
1. Product Description
The ABB TY801K01 (model number: 3BSE023607R1) is a dedicated terminal unit designed for ABB’s S800 I/O system, serving as a critical bridge between field - level sensors/actuators and the core I/O modules. Unlike standard terminal units, it integrates signal conditioning, secure wiring management, and system - level compatibility, specifically optimized for analog and digital signal transmission in industrial automation scenarios.
Engineered with industrial - grade materials and anti - interference circuitry, the TY801K01 ensures stable signal integrity even in harsh environments characterized by electromagnetic interference (EMI), temperature fluctuations, and mechanical vibration. It supports standardized terminal connections for easy field wiring, while its modular design enables seamless integration with S800 I/O modules (e.g., AI523, DI524) and upper - level controllers (AC 800M DCS).
Widely applied in process control, discrete manufacturing, and energy infrastructure, the TY801K01 provides a reliable, cost - effective solution for signal termination, protection, and distribution—critical for maintaining the accuracy and responsiveness of industrial control systems.
2. Detailed Parameters
3. Advantages & Features
- Dual - Signal Compatibility & Signal Integrity
Supports both analog (4 - 20 mA, 0 - 10 V) and digital (24 V DC) signals, eliminating the need for separate terminal units for different signal types. Tin - plated copper terminals minimize contact resistance, ensuring analog signal accuracy (±0.1% full - scale deviation) and digital signal responsiveness (≤1 ms delay), critical for precision control scenarios (e.g., chemical reactor temperature monitoring).
- Robust Isolation & Anti - Interference
500 V DC signal - to - ground isolation prevents cross - talk between adjacent signals, while 1500 V DC signal - to - power isolation protects the unit from voltage surges (e.g., from field wiring faults). Built - in EMI filters comply with IEC 61000 - 6 - 2, suppressing noise from nearby high - power equipment (motors, inverters) and maintaining signal stability in electrically noisy environments.
- Easy Wiring & Maintenance
Standardized screw - type terminals with clear numbering enable quick wire identification, reducing wiring time by up to 30% compared to non - labeled terminals. The 0.5 - 0.8 Nm torque range balances connection security and wire protection, avoiding over - tightening damage. Additionally, the compact DIN rail design saves control cabinet space, simplifying module layout and future expansions.
Modular design ensures plug - and - play compatibility with S800 I/O modules—no additional adapters required. It aligns with S800’s backplane communication protocol, enabling the terminal unit to be recognized by the AC 800M DCS for status monitoring (e.g., wiring fault alerts). This integration reduces system complexity and ensures consistent performance across the S800 ecosystem.
- Industrial - Grade Durability
- 40℃ to + 70℃ operating temperature range adapts to extreme environments, from freezing outdoor substations to high - temperature metallurgical workshops. Vibration and shock resistance (IEC 60068 standards) ensure reliability in mobile equipment (e.g., on - site process skids) or vibrating production lines (e.g., automotive assembly).
4. Application Fields
- Process Control (Chemical/Pharmaceutical)
Used in chemical plants to terminate 4 - 20 mA signals from pressure transmitters (reactor/vessel pressure) and 24 V DC digital signals from valve position switches. The isolation feature prevents signal interference between corrosive chemical processing units, ensuring accurate pressure monitoring and valve status feedback.
- Discrete Manufacturing (Automotive/Electronics)
Deployed in automotive assembly lines to connect 0 - 10 V analog signals from robotic arm position sensors and 24 V DC digital signals from proximity sensors (part presence detection). The terminal unit’s signal integrity ensures precise robotic movement and reliable part tracking, supporting high - speed production.
- Energy & Power Generation
Integrates with S800 I/O systems in thermal power plants to terminate Pt100 RTD signals (turbine bearing temperature) and 4 - 20 mA current signals from steam flow meters. Its wide temperature adaptability withstands power plant heat cycles, while anti - interference design resists EMI from generators.
- Water & Wastewater Treatment
Used to terminate 4 - 20 mA signals from dissolved oxygen sensors (aeration tanks) and 24 V DC digital signals from pump contactors. The secure wiring management prevents water damage to connections, ensuring continuous monitoring and control of treatment processes (e.g., sludge dewatering).
- Food & Beverage Processing
Applied in food factories to connect 0 - 10 V analog signals from temperature sensors (pasteurization units) and 24 V DC digital signals from conveyor belt emergency stops. The terminal unit’s compliance with food industry standards (e.g., IP20 for cleanroom compatibility) ensures it meets hygiene and safety requirements.
