D1600 Frequency Input Modules



The  D1600 ADC module converts frequency and pulse sensor input signals to digital information, linearizes the digital data, scales the data 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 D1600 series modules can also be mounted on a DIN-Rail using the MK-1 mounting kit.
