Modbus RTU Analog Input Modules
-
The Datexel range of Modbus RTU analog input cards for both RS485 and RS232 with Modbus or ASCII protocol can be combined with the DAT9000 series of Modbus Masters. A choice of input cards or modules are available and have various optional inputs such as Voltage, Current, Thermocouples, RTD, and Resistance. Also a choice of 2, 4, 8 channel options are available. The DAT3011 is a Modbus RTU Slave with 1 selectable universal input (Thermocouples, RTD, mV, RTD's or Resistance), 2 x 4-20mA or 0-10V input and 2 x4-20mA outputs. The DAT3011 also has 3 digital inputs and 3 relay outputs. Each module is isolated from each other and is set up using the DAT3000 software Development package which is free of charge from the Datexel download web page. Datexel also has universal input modules. An 8 channel analog input card is available making the DAT3000 series a very economical solution to large and small scale Data Acquisition. Combining these analog input cards with the analog output cards, the digital input/output cards and the communication devices make Datexel the smart choice where Data Acquisition is required.
