NTC-X9-LFX: Non-Isolated Frequency Transmitter

Function:

The NTC-X9-LFX is a microprocessor based frequency transmitter. It has one analog input and a square wave output. The output frequency is adjustable from 0-500Hz to 0-1000Hz for 0-100% of input signal. The output frequency is linear with respect to the input signal.

A low-end frequency cutoff turns off the output frequency below 15% of input signal. For a 0-20mA input range this means that the output frequency will turn off below 3mA.

Specifications:

• Accuracy/Linearity:+/- 0.3% max., +/- 0.1% typ.
• Operating Temperature: -40 Deg.C. to +50 Deg.C.
• Temperature Effects: +/-0.5% max., +/-0.2% typ.
