Modbus Controllers.

Datexel offers a full line of Modbus controllers for RTU and TCP communication networks. These advanced Modbus master devices support flexible I/O, remote data acquisition, and integrated data logging. The DAT9000 series includes models with RS485, RS232, and Ethernet ports, ideal for managing Modbus RTU and Modbus TCP protocols. Variants like the DAT9000IO add digital I/O, while the DAT9000DL adds Data logging. The DAT9000DLIO combines both features in one unit.

The DAT9011 is a versatile Modbus RTU master controller with two analog inputs (supporting thermocouples, RTDs, potentiometers, mA, and mV), two current analog outputs (4-20 mA ), digital inputs, and dual relay outputs. The DAT9011DL provides logging to USB drives (up to 8 GB), supporting both internal and external Modbus register logging.

All Modbus controller models are configured via Ethernet using Datexel's free development software, available from our Download Page.

DAT9550 Datasheet

Yes, the DAT9011 Modbus controller can read two Modbus registers and convert them into two 4-20 mA outputs.

You can use the DAT9000 Modbus master to read multiple registers and send the values to a DAT3024ISO module, which provides up to four 4-20 mA outputs.

Yes, both the DAT9000 and DAT9011 can work with a DAT3024ISO to provide up to four analog outputs, which can be configured for either 4-20 mA or 0-10 V signals.

You can use one DAT9000 controller to read 20 Modbus registers and then use five DAT3024ISO modules to convert them into twenty 4-20 mA or 0-10 V outputs.

Yes, the DAT9000 and DAT9011 can read 32-bit floating point registers and convert the value to a 4-20 mA analog output.
