MTN682191 Schneider SpaceLogic KNX Analogue Input Module REG-K 4-Gang BAS Building Automation Component
Product Description & Introduction
Schneider MTN682191 is a high-precision 4-gang analogue input module from the SpaceLogic KNX REG-K series, designed as a core data acquisition component for Building Automation Systems (BAS). Its primary function is to convert real-world analogue signals (from sensors measuring temperature, brightness, pressure, current, etc.) into KNX bus-compatible digital signals, enabling real-time monitoring of building environmental parameters and equipment operating status. This data forms the foundation for automated linkage control of lighting, HVAC, and security systems, making it an essential part of intelligent, energy-efficient building solutions.
Key Advantages
- 4-Channel High-Density Acquisition
Supports simultaneous collection of 4 independent analogue signals, reducing the number of modules needed for multi-sensor scenarios and improving system integration efficiency.
- REG-K Architecture for Reliability
Built on Schneider’s REG-K technical platform, it features industrial-grade anti-interference design and high signal acquisition accuracy, ensuring stable performance in complex building environments.
- KNX Global Standard Compatibility
Fully compliant with KNX TP1 protocol, it seamlessly integrates with all KNX-certified devices and supports configuration and debugging via KNX ETS 5/6 software, enabling flexible system expansion.
- Compact & Discreet Design
Light grey 2-module DIN rail-mounted housing fits neatly into standard electrical control cabinets, saving installation space while blending with the aesthetics of modern building control systems.
- Wide Signal Range Support
Compatible with common industrial analogue signals (0-10V, 4-20mA, etc.), making it adaptable to a variety of sensor types and project requirements.
