ModBus RTU Master DAT9000

General Description

The Modbus RTU Master DAT9000 is a Data Acquisition and controller unit that can be used as a Modbus Master or Modbus Slave. The DAT9000 also has an Ethernet 10 Base-T MODBUS TCP Interface, along with RS485 Master and Slave ports, and an RS232 port. It is possible to program the DAT9000 to read registers and process logical and mathematical functions, enabling the DAT9000 to provide linearization, scaling, averaging and square root extraction, to name a few. It can be used in conjunction with other Modbus devices.
