            Data Logger ML28 This device records the ON/OFF status of digital signals. Data is continuously stored in the internal memory, accompanied by timestamps indicating when the events occurred. It is suitable for installation where monitoring the operational status of machinery-such as pumps, motors, or chillers-is required.

            Data stored in the ML28 can be read by connecting a computer to the ML28 via an RS232 port or a modem, using software to read the data into the computer. The obtained data can then be displayed on the computer as numerical data or as graphs. This data can also be used in other Windows programs such as MS Excel, making it convenient to use.
