MBU-80 has its own RS-485 communication port and adopts the standard MODBUS communication protocol. Through the communication port, all measurement and monitoring information can be queried. There are LED indicators on the LCD panel and back for communication reception/transmission indication.
The 1 DC4-20mA internal excitation/transmit output object is optional and the output load is 500Ω
It can be expanded to 4 switch inputs; optical isolation inputs; active node inputs; and a switch input indicator on the LCD panel.
Up to 2 outputs; contact capacity: AC250V /5A DC30V /5A; control mode: remote and local modes; local self-control mode can set various fixed action conditions; output mode: level or pulse (pulse width 0—255 seconds) with relay on/off indicator on LCD display panel.
