Building Management System BMS - building automation

Building Management System BMS – Comprehensive Solutions for Automation and Integration

A Building Management System (BMS) is a centralized platform that enables intelligent monitoring and control of building infrastructure, such as HVAC, lighting, access, and energy. To ensure smooth data exchange and automation across different technologies, a BMS requires specialized converters, communication modules, and industrial networking equipment. At CONSTEEL, we offer a full range of industrial-grade solutions to support efficient, reliable, and scalable BMS deployments.

M-Bus Converters – Integrating Energy and Water Meters

M-Bus to Modbus converters enable BMS platforms to retrieve real-time readings from thermal, electric, gas, and water meters. They are essential for accurate energy monitoring, cost allocation, and integration with building analytics systems.

DALI Converters – Smart Lighting Management

DALI converters support the integration of lighting systems into the BMS architecture. They offer advanced control over individual luminaires, groups, and scenes. These devices help reduce energy costs and enhance occupant comfort through automation.

BACnet, Modbus, KNX Converters – Multi-Protocol Communication

Our protocol converters bridge communication between BACnet IP, Modbus RTU/TCP, and KNX systems. They are key components for linking HVAC units, lighting controls, fire systems, and access control into a unified BMS dashboard.

AC Communication Modules – BMS Control for Air Conditioning

Specialized communication modules allow direct integration of split units and VRF/VRV air conditioners (Daikin, LG, Mitsubishi, etc.) into BMS networks. These devices enable centralized temperature, mode, and schedule control across all zones.

I/O Modules – Digital and Analog Signal Handling

Input/output modules expand the control capabilities of your BMS. They collect signals from sensors and switches, and control actuators, fans, relays, or dampers. Ideal for HVAC, alarm, shading, and access control systems.

Industrial Switches – Reliable Ethernet Networks

Our industrial-grade Ethernet switches are designed for high-performance BMS networks. They feature wide temperature ranges, redundant power supply, VLAN, QoS, and ring redundancy support – ensuring network stability in harsh environments.

Serial Device Servers – Integration of RS232/RS485 Devices

Serial servers allow legacy devices with RS232 or RS485 interfaces to communicate over IP-based BMS platforms. Perfect for extending the life and connectivity of meters, controllers, and older field devices.

Fiber Media Converters – Long-Distance Communication

Fiber media converters provide reliable data transmission over long distances and ensure electromagnetic interference resistance. Crucial in large buildings, campuses, and industrial areas where wired Ethernet cannot reach.
