Modbus Data Logger DAT9011DL

General Description Modbus Data Logger

The Modbus Data Logger DAT9011DL and DAT9011USB are Data Acquisition units that can store registers that are on a Modbus RTU network. The DAT9011DL stores registers to an SD Memory card and the DAT9011USB stores to a USB Flash drive.
The DAT9011DL and DAT9011USB also have analog inputs such as Thermocouples, 4-20mA, volts, RTD's, Resistance, Potentiometers and 2 4-20mA outputs. They also have 2 Digital inputs that can work up to 300Hz and 2 relay outputs.
The DAT9011DL and DAT9011USB have built in Modbus master and Modbus slave ports, and can work on RS485, RS232 and Ethernet Communication.
Simply connect to the DAT9011 DL or DAT9011USB Modbus Data Logger with an Ethernet cable and the Free Dev9 development software and set up the logger to collect information on the MODBUS network or log the internal analog and digital input channels. Various function blocks are available to condition the parameters such as Communication, which handles the reading and writing of the registers from external devices. Also maths function blocks that can add, subtract, multiply, divide, scale, and average. Other function blocks are move, shift, trip, alarms and timers.
Other Datexel modules can be used in conjunction with the DAT9011DL and DAT9011USB such as the DAT9550 which is a Remote Display unit that can display pages of different parameters and the DAT3000 range of Analog and Digital inputs and outputs.
See the Download page for many Application Notes, User Guides, and the Free Dev9 software development tool.
