The BusWorks XT series of Ethernet I/O modules support Modbus TCP/IP, Ethernet/IP, Profinet and i2o peer-to-peer communication protocols. They monitor and/or control up to 16 discrete or analog devices per unit with a variety of inputs and outputs supported.

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.
