Schneider Electric MNB-CNTLR-15 Remote I Module

Schneider Electric MNB-CNTLR-15 Remote I/O Module is the controller electronics for the MNB-1000-15 MicroNet BACnet Remote I/O expansion in the TAC I/A Series. It provides six universal inputs, three universal outputs, and six digital outputs (triacs) to extend the MNB-1000 controller’s I/O capacity. The unit operates on a 24 VAC Class 2 power supply, with each digital output rated for up to 12 VA at 24 VAC, enabling direct control of low-power loads. Designed for BACnet MS/TP networks, the MNB-CNTLR-15 integrates with Schneider Electric’s MicroNet architecture to support distributed sensing and control for HVAC, lighting, and other building systems. When used with an MNB-1000 controller, you can connect up to eight remote I/O modules, adding up to 120 I/O points (8 × 15). This electronics module is intended to pair with the MNB-1000 base and, if desired, an MNB-300-ENC enclosure for wall mounting. The MNB-CNTLR-15 is part of Schneider Electric’s TAC I/A Series MicroNet family, offering scalable I/O expansion for mid- to large-scale commercial installations that require BACnet interoperability and distributed control.
