Transmitters: TT230 Series TT239 Frequency/pulse/PWM input two-wire transmitter
■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 conneciton
■High-voltage isolation separates the input from the output circuit. Isolation protects from surges, reduces noise, and eliminates ground loop errors.
■Setup and calibration are fast and easy with a convenient USB connection to your PC and Acromag’s Windows configuration software
■Advanced signal processing capabilities, variable range input, and convenient USB programming make this instrument a very versatile frequency measurement device. These transmitters can withstand harsh industrial environments and operate reliably across a wide temperature range with very low drift. They feature RFI, EMI, ESD, EFT, and surge protection plus low radiated emissions.
●Key Features & Benefits
■Easy setup and digital calibration via USB with Windows configuration software
■Measures frequency or duty cycle and interfaces many input types up to 100KHz
■Accepts input amplitudes up to 120Vrms(±170V DC, unipolar or bipolar)
■Adjustable 0Hz cut-off, sample averaging, and output update time
■Software configurable pull-up/down resistors (+4V DC input pull-up for sensors/transducers)
■1500V isolation between input/output circuits
■Space-saving 12.5mm (0.5 inch) unit with pluggable terminals for convenient wiring
■Fast response time and high accuracy
■Supports normal or reverse-acting output
■Supports sink or source output wiring
■NAMUR-compliant output loop current
■Shock (25g) and vibration (4g) resistant
■Wide ambient operation (-40 to 80°C)
■CE compliant. UL/cUL Class I Div 2, ATEX / IECEx Zone 2 approvals
