Bộ điều khiển chuyên dụng cho chiếu sáng

The MACH-ProLight is a freely programmable and scalable BACnet Building Controller (B-BC) that provides 0– 10 V continuous dimming and BACnet binary lighting output (BLO) object support. This allows you to implement advanced control strategies such as daylight harvesting, dim-to-off control, vacancy control, plug-load control, and scene/theme control, key strategies for achieving OpenADR and Title 24 compliance. Compatible with standard lighting control relays, low-voltage peripherals, EnOcean wireless products, and Reliable Controls SPACE-Sensor™ Temperature and SMART-Sensor™ products, the MACH-ProLight ships in a convenient preassembled UL 508A Listed control panel or as individual components.
