The D1600 modules measure frequency and pulse signals from industrial sensors. The frequency input modules can measure frequency signals between 1hz-20Khz. The pulse input modules measure the pulse width of signals between 100 microseconds and 30 seconds. Both unipolar and bipolar signals can be measured.
The D1600 series includes an accumulator version of the frequency and pulse input modules. The accumulator versions measure the instantaneous frequency and totalize the number of cycles or pulses that the module has measured. An internal counter is used to count the number of cycles or pulses. The counter can be read or cleared at any time. It can also be read and cleared at the same time. The frequency accumulator module measurement range is 1hz-10Khz.
The D1600M frequency input modules include one discrete digital input for monitoring contact closures or switches. The discrete digital input contains an internal pull up resistor and can accept +/-30Vdc signals without damage. The discrete switching levels are <+1Vdc = logic “0”, >+3.5Vdc equals a Logic “1”.
The scaled data values are communicated to a host computer via an RS-232 or RS-485.

The D1600 Frequency input modules can be mounted on a DIN-Rail using the MK-1 mounting kit.
