NC24A RS485 Modbus RTU networking LCD universal controller applies communication technology of Modbus RTU master/slave protocol to monitor and supervise year around air conditioning units in commercial, industrial and residential Installation. Measurement and control of temperature, relative humidity, absolute humidity, enthalpy, pressure differential, volumetric airflow and indoor air quality. The input scale can be set from –99 to 999 units. The start and end points of output voltage can be any value between 0 to 10 VDC.
The maximum number of NC24A slaves in a Modbus RTU network is 32. Optional BACnet MS/TP Gateway module (BMG-NC24A) is available for order. It works as an interface to link up the NC24A controllers with BACnet MS/TP communication bus. Please refer to the product bulletin of BMG BACnet MS/TP Gateway for details.
