BFC series controllers



(A)

(B)
 Product Introduction
The BFC series controllers work on the MS/TP BUS specifiedbyBACnetprotocol, and communicate at up to 76.8Kbps.Thesecontrollers canseamlessly integrate with other companies’productscomplying withBACnet, and can be integrated into MODBUS,CBUS,PROFIBUS and othernetworks through the gateways or thethird-partyinterfaces.

 Product Properties
 Compatibility – Fully compatible with the BACnet,caninterconnectwith the products complying with BACnet protocol,andthe MS/TP BUScommunication speed can be up to 76.8Kbps.
 Universality – Can freely program & download thecontrollogicaccording to the field control requirements.
 Reliability – The application programs and hard-wares arestoredinthe nonvolatile storage to effectively ensure theprogramsafety.
 Usability – Write the program with the graphicalfunctionmodules,easy-to-learn & use.
 Rapidity – The program internal logical loop periodisonly100msec.
