The BIOM networking input/output field modules provide remote analog inputs/outputs to any native BACnet MS/TP controllers. Each BFM field module communicates on a RS-485 network at its communication port using the BACnet MS/TP protocol technique.

 

The BIOM Series field modules fit a diverse range application needs where additional analog or binary inputs and outputs are required or where a small number of analog points are remotely located.

 

All analog inputs are protected with optical isolation devices from external interference.

The BMGE is a network gateway module which routes communication traffic between BACnet Ethernet network and Modbus RTU network.

 

The gateways, pre-loaded with a Modbus program, become masters to the connected Modbus slave    devices and communicate using the Modbus RTU protocol on a RS-485 network.

 

Each gateway is available with two RS-485         networks. Each network can support up to 32 Cyrus Controls NT10, NT50, NC24A,  NC24T or NSM Modbus RTU devices. These devices must not be mixed in both network trunks and must be of the same series or type.

 

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.
