Designed and developed for interfacing with a PLC or PC environment, it is directly supplied with the service 24Vdc thanks to its internal optically-isolated supply voltage.
W-Bus consists of the main Mother Board, optional Bus board used to install optional boards, 4 types of optional boards and optional Remote Terminal with display and keyboard.
Currently, 4 optional boards are available: BCD Output Card, Analogue Output 4 ÷ 20mA Card, RS232C Card and RS485 Card. The optional boards are selected according to the weight to be transmitted to the PLC/PC.
