Transmitter, Frequency/Pulse/PWM Input, 12-32V DC Loop/Local Power
• Multi-range 0Hz to 100KHz frequency input
• Multi-range 0Hz to 3KHz PWM input
• 4-20mA output (sink/source)
• 12-32V DC power
The TT239 model is a space-saving two-wire transmitter that isolates and converts a frequency, pulse, or pulse-width modulation (PWM) input to a proportional 4-20mA signal. You can select to measure either the input frequency or the duty cycle. Power is received from the output loop current or a DC suply when using a three-wire connection.
High-voltage isolation separates the input from the output circuit. Isolation protects from surges, reduces noise, and eliminates ground loop errors.
