BACnet to Modbus HVAC Protocol Converter BL120BN
Basic Version: 2 Serial Ports: BL120BN
P Version: 6 Serial Ports: BL120BNP
BL120BN HVAC BACnet protocol converter is designed to transmit communications from BACnet devices to Modbus devices for building automation.
A typical scenario in industrial applications is integration of BACnet/IP or BACnet MS/TP devices into a Modbus TCP or Modbus RTU installation.
⚪Downlink Supports BACnet/IP, BACnet MS/TP
⚪Uplink Supports Modbus RTU, Modbus TCP
⚪Supports SNMP V1/V2
⚪Supports transparent transmission
⚪RJ45 Ethernet ports
⚪RS-485/232 serial ports
⚪Supports OpenVPN
⚪Supports 4G communication
⚪Supports WiFi, routing functions and cascading switch
⚪Supports remote configuration and firmware upgrade
All BL12x series gateways support 4G/WIFI/GPS/, and the number of serial ports can be selected from 2 serial series or 6 serial ports. The selection table is shown in Table 1 below.
