For the management of up to 8 tasks of storage data, there are mathematical functions necessary for system operation the device DAT9011-DL is an intelligent control unit for the network slave Modbus RTU devices that are connected on a serial line. The microSD card is where the data is saved. By means of Ethernet connection you can gain access to the saved files. The device has two relay outputs, two digital inputs, and one channel mA and Volt input and one universal analogue input channel. For the supply of passive sensors on the field there is an input on the Auxiliary source. This can occur through the RX-485 SLAVE or RS-232 ports or through the Ethernet interface. It's possible for reading and writing in real time through the internal registers values.
