DESCRIPTION
A four-channel input module for use with tachometers, flowmeters and other transducers that have
frequency output. It can also measure the period between events and count or totalize events.
The 6048 accepts TTL inputs, which are optic isolated or input signals from 100mV to 100 Volts, which
trigger on zero crossing. It can measure frequency to 350 kHz, measure period down to 10 nS and count
events in excess of 4 billion.
