ABB TVOC-2-240 (1SFA664001R1001) Air Quality Control Module

Product Overview

The ABB TVOC-2-240 (Part No. 1SFA664001R1001) is a high-sensitivity TVOC air quality control module, a core component for ABB environmental monitoring and building automation. It integrates high-precision sensing, signal processing and communication output functions. Designed for indoor and outdoor air quality monitoring, HVAC linkage and smart building management, it accurately detects Total Volatile Organic Compound (TVOC) concentrations and delivers reliable data for healthy spaces and energy-efficient operation.

Key Features

• Precise & Highly Sensitive Detection Equipped with premium VOC sensing elements, it features a measuring range of 0–100 ppm and accuracy of ±5% of reading. It can detect trace-level VOCs emitted from decoration materials, furniture and cleaning agents, perfectly suited for low-concentration pollution scenarios in buildings.
• Fast Response & Real-time Linkage Response time ≤ 30 seconds to quickly capture concentration changes. It can be directly linked with HVAC and fresh air systems to dynamically adjust airflow, balancing indoor air quality and energy costs.
• Industrial Stability & Wide Application Range Operating temperature: -20°C to 50°C. With strong anti-electromagnetic interference capability, it adapts to complex environments such as office buildings, shopping malls, hotels, hospitals and laboratories. Rated IP20. Available in wall-mounted and duct-mounted styles for easy maintenance.
• Multiple Outputs for Seamless BMS Integration Supports 4–20 mA analog output and Modbus RTU digital communication. Compatible with PLC, DDC, IoT platforms and building management systems to realize data visualization, remote monitoring and automatic alarm.
• Low Power Consumption & Maintenance-Free Performance Powered by 24 V DC ±10% with power consumption ≤ 50 mA. Factory pre-calibrated with minimal long-term drift. Frequent recalibration is not required, effectively reducing operational costs.
• Integrated Design for Easy Installation & Commissioning Compact structure with pluggable terminals and a simple built-in HMI. It supports DIN rail mounting and wall mounting, enabling quick on-site configuration and parameter checking.
