Van Essen Instruments Diver-MOD

The Diver-MOD is the Modbus interface used to connect Divers to an RS485 network. The Diver-MOD is the Modbus interface for Divers and is used to connect Divers to an RS485 network using the Modbus/RTU protocol. The Diver-MOD features a barometric sensor, which can be used to convert the Diver pressure in to a water level. A typical Modbus configuration is illustrated in the figure below. In the schematic, two Diver-MODs are connected to a PC/PLC. This connection includes both data communication and power. The maximum Modbus cable length depends on the baud rate, the cable, the network configuration (2-wire or 4-wire), etc. A maximum length of 1000 meters can be achieved using the right components.
