Schneider Electric MNB-70 Micronet BAnet Controller

Schneider Electric MNB-70 TAC MicroNet BACnet Zone Controller is an I/A Series device that provides BACnet MS/TP interoperability for HVAC equipment such as rooftop units, fan coils, heat pumps, and small unit vents. It configures with three universal inputs (UI1–UI3), one universal output (UO1), and three triac outputs (DO1–DO3) plus Sensor Link (S-LK) sensor support, enabling compact, zone-level control for single or dual loop systems; it uses a DIP switch to set MS/TP network addresses and is BACnet MS/TP capable. Powered from a 24 VAC Class 2 supply (20.4–30 VAC, 50/60 Hz), it draws about 15 VA per controller plus DO load and is BACnet‑BTL listed for I/A Series MicroNet BACnet Zone Controllers, with configuration tooling via Schneider Electric WP Tech Tool.
