Modbus Data Logger with Digital IO DAT9000DLIO

General Description

The Data Logger DAT9000DLIO is a Data Acquisition unit with a built in SD Ram port that can take a Micro SD card. The DAT9000DLIO also has 4 digital inputs and 2 relay outputs. The DAT9000DLIO is a Modbus master and Modbus slave and has RS485, RS232 and Ethernet Communication ports. The DAT9000DLIO can control a network of slaves and perform logical and mathematical functions. The DAT9000DLIO can save the internal registers value on to the SD card. It is possible to remove the card for analysis or use the Ethernet port to retrieve the saved values on the SD Ram.
