TT239: Frequency / Pulse / PWM Input, 12-32V DC Loop Power, 2-Wire Transmitter
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 supply when using a three-wire connection.

TT339: Frequency / Pulse Input, 12-32V DC Local/Bus Power Transmitter
Multi-range 0Hz to 100KHz input
Universal current/voltage output
12-32V DC local/bus power
The TT339 model is a space-saving four-wire transmitter that isolates and converts a frequency or pulse input to a proportional control signal. DC current and voltage output are both supported on a single model. An optional DIN rail bus can deliver primary or redundant power to multiple units without wiring.
