DT335: RTD / Resistance Input Four-wire Dual Transmitter Description

DT330 series signal conditioners provide two independent I/O channels in a single, space-saving unit.

The DT335 model is a four-wire dual transmitter that isolates and converts RTD or linear resistance sensor inputs to proportional control signals.

Each channel supports DC current or voltage output. An optional DIN rail bus can deliver primary or redundant power to multiple units.

High-voltage isolation separates inputs, outputs, and power from each other. 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. The Android app enables setup with mobile devices.

Advanced signal processing capabilities, variable range input/output, and convenient USB programming make this instrument very versatile.

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.

DT335: RTD/Resistance Input Four-wire Dual Transmitter Features & Benefits

IMPORTANT: To prevent damage or errors from grounded PCs and surges, Acromag strongly recommends use of a USB isolator like Acromag’s USB-Isolator when configuring a DT330 Series transmitter.

  • Operate as a dual transmitter, a single transmitter, or a signal splitter
  • Easy configuration via USB with Windows software or Agility™ app for Android
  • Independently adjustable and scalable input and output ranges
  • Selectable RTD and linear resistance input types: Pt 100/200/500Ω, Ni 120Ω, Cu 10Ω, 0-4500Ω
  • Supports 2, 3, and 4-wire sensor connections
  • Selectable current and voltage output ranges: 0-20mA, 4-20mA, ±5V, ±10V, 0-5V, 0-10V DC
  • High accuracy, linearity, stability, and reliability
  • User-selectable filtering (none, low, med., high)
  • Selectable up/downscale break detection
  • Bus power, local power, or both (redundancy)
  • Space-saving 17.5mm (0.7 inch) unit with pluggable terminals for convenient wiring
  • 1500V input isolation, 5-way, (power/input/output)
  • Wide ambient operation (-40 to 70°C)
  • CE compliant. UL/cUL Class I Div 2, ATEX/IECEx Zone 2
