The D2600 ADC module converts frequency and pulse signals to digital information and scales the data in customer programmed values, and communicates the values to a host computer or PLC. The data values are transmitted in ASCII to a host computer via RS232 or RS485.

The D2600 series modules can also be mounted on a DIN-Rail using the MK-1 mounting kit.
