The Model IL40A is a single-channel conditioner which accepts any AC or unipolar pulse input,

irrespective of waveform, from turbine flow meters, magnetic pick ups or similar frequency-generating

transducers. The frequency source can be grounded or floating. For environments which may have high

frequency noise or a DC offset on the input signal, the IL40A contains input suppression and DC offset

capacitive coupled signal termin

als. When used with an open-collector type sensor, the IL40A requires

a pull-up resistor (typically 10k Ohms) between + Signal and + Excitation.

Sensitivity Operation: The IL40A contains four selectable input sensitivity ranges which allows the

user to accommodate input signal levels to the IL40A's "Smart Schmitt" trigger circuit for signals as

low as 50 millivolts ( i.e. low flow turbine meters) and up to inputs as high

as 250 Volts as seen in

magnetic speed sensors.

The Model IL40A is calibrated by means of a “two-point (dead-weight)” process involving a known

frequency standard or through the use of the "F CAL" reference provided.
