Benefits of the MC Series Modbus Controllers
- Modbus controllers for various I/Os - ideal solution for building-management systems (BMS), process controllers, IoT/IIOT etc.
- Communicate over Modbus RTU via RS485.
- Low power consumption and compact design.
BRTSys MC Series Relays, I/O Controllers and Lighting Control
The BRTSys MC series is a family of Modbus controllers including relays, I/O controllers and lighting dimmers. All version implement the Modbus RTU protocol: The devices communicate over Modbus RTU via RS485, enabling integration into building-management systems (BMS), process controllers, IoT gateways, and wireless bridges, for communication via protocols such as LoRaWAN. All versions have flush mount and DIN rail mount options.
Models and versions:
Model Overview
| Model | Description | Product group | |
| BRTSys MC-0111-01A | Modbus 2-channel relay | 2-cannel changeover relays with latching feature to retain state across reset/power cycles. Switching of high current AC and DC loads (up to 16 A) such as motors, pumps, fans, valves, alarm circuits | Actuator |
| BRTSys MC-0101-01A | Modbus 2-channel relay + iSENSE | 2-channel changeover relays with latching feature and load current sensing. Switching of high current AC and DC loads (up to 16 A) such as motors, pumps, fans, valves, alarm circuits. Additional load current sensing on each channel (up to 20 A) | Actuator |
| BRTSys MC-0102-01A | Modbus 4-channel SSR/solid state relay | 4 channels of solid-state switching. Silent switching of loads with zero-crossing detection. Ideal for controlling lighting control, signage, or other low-load AC devices | Actuator |
| BRTSys MC-0601-01A | Modbus isolated I/O controller | Isolated I/O: 2 digital inputs, 2 digital outputs, 2 analog inputs, 2 analog outputs. Integrate legacy sensors or custom I/O into a Modbus-based automation system, such as analog devices (0...10 V or 4...20 mA for example), digital devices or dry contacts | Actuator |
| BRTSys MC-0301-01A | Modbus trailing edge light dimmer | Dimming control for AC LED luminaires, with smooth trailing edge dimming. Suitable for smart lighting in buildings, hotels, offices, or retail spaces. Control via Modbus or locally via up/down buttons and switch inputs | Actuator |
