Low-Current Systems

Service Scope

Low-current cabling requires organized routes and correct termination for BMS infrastructure, automation, data and communication systems to operate properly. MDF Elektrik installs RS485 cabling, Modbus/BACnet lines, sensor connections, device supplies and panel signal wiring on routes separated from power cables. Cable type, shielding and labeling are checked on site to reduce interference, signal loss and addressing errors.

Application Details

• RS485 cabling and Modbus/BACnet communication lines
• Field device, sensor and DDC panel connections for BMS infrastructure
• Separate routing for data, communication and control cables
• Shielded cable, grounding and interference checks
• Device addressing, labeling and continuity tests

Application Process

1. 1BMS points, device lists and automation drawings are compared with site teams.
2. 2RS485 cabling and low-current routes are separated from power cables.
3. 3Sensor, actuator, meter and DDC panel connections are completed with labeling.
4. 4After continuity, polarity and communication checks, the system is handed over to the automation team.
