Schneider MTN682291 Product Description
Schneider MTN682291 is a high-performance 8-gang analogue input module belonging to the SpaceLogic KNX REG-K series, a core data acquisition component tailored for professional Building Automation Systems (BAS). As the high-channel extension model of the REG-K analogue input product line, it is engineered to convert real-world analogue signals (from temperature, brightness, pressure, current, flow and other industrial sensors) into KNX bus-recognizable digital signals with high precision, realizing real-time and synchronous collection of 8 groups of independent physical parameters. The collected data is transmitted to the KNX main control system to provide reliable data support for the automatic linkage control of lighting, HVAC, ventilation, and energy monitoring subsystems, making it an ideal choice for medium and large-scale intelligent building projects that require multi-point parameter acquisition.
Inherited from Schneider’s REG-K series industrial-grade design, the module features galvanically isolated channels to avoid signal interference between different acquisition points, ensuring stable and accurate data transmission even in complex building electrical environments. It is fully compliant with the global KNX TP1 protocol, can be seamlessly integrated with all KNX-certified automation devices, and supports flexible parameter configuration and on-site debugging via KNX ETS 5/6 software—realizing customized signal range setting for each channel according to project needs. With a compact 4-module DIN rail-mounted structure and a light grey housing, it fits neatly into standard electrical control cabinets, saving installation space while matching the aesthetic layout of modern building control systems, and is easy to integrate and expand with other KNX REG-K series modules.
Key Core Advantages
- 8-channel high-density acquisition: Supports simultaneous collection of 8 groups of independent analogue signals, reducing the number of modules used in multi-point acquisition scenarios and improving the integration efficiency of BAS system wiring and cabinet layout.
- Galvanic isolation between channels: Effectively isolates cross-interference between different sensor signals, ensuring the accuracy and reliability of acquisition data, and adapting to complex industrial and building electrical environments.
- Industrial-grade precision performance: 12-bit high resolution and high linearity acquisition, with small full-scale error, can accurately capture subtle changes in analogue signals and meet the high-precision parameter monitoring requirements of intelligent buildings.
- Full KNX standard compatibility: Compliant with KNX EN 50090 protocol, supports ETS software configuration, and can be seamlessly connected with Schneider SpaceLogic series and other KNX-certified devices, with strong system expandability.
- REG-K series consistent design: Inherited from the mature REG-K technical architecture, with excellent anti-interference and environmental adaptability, IP20 protection level, and stable operation in the mainstream working temperature range of buildings.
- Easy installation and maintenance: 35mm standard DIN rail mounting, plug-and-play KNX bus connection, no additional power supply required, and convenient later system maintenance and module replacement.
