Product short description:
  • Dual channels
  • RTD (Pt, Ni, Cu), 0-4500 ohm inputs
  • 4-20mA output (sink/source)
  • 7-32V DC loop power

The DT235 model is a two-wire dual transmitter that isolates and converts RTD or linear resistance sensor inputs to a proportional 4-20mA control signal.

RTD / Resistance Input Two-Wire Dual Transmitter Description

DT230 series signal conditioners provide two independent I/O channels in a single, space-saving unit.

The DT235 model is a two-wire dual transmitter that isolates and converts RTD or linear resistance sensor inputs to a proportional 4-20mA control signal.

Power is received from the output loop current or a DC supply when using a three-wire connection.

High-voltage isolation separates all input and output circuits 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.

RTD / Resistance Input Two-Wire Dual Transmitter Features & Benefits

IMPORTANT: To prevent ground loop error between a grounded PC and a grounded input signal, Acromag strongly recommends use of a USB isolator like Acromag’s USB-Isolator when configuring a DT230 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
  • 4-20mA current loop outputs support sinking or sourcing circuit configurations
  • Supports reverse-acting (inverse) output
  • User-configurable output range clamp levels support NAMUR-compliant operation
  • Selectable up/downscale sensor break detection
  • Very low 7V two-wire loop burden
  • High accuracy, linearity, stability, and reliability
  • User-selectable filtering (none, low, med., high)
  • Space-saving 17.5mm (0.7 inch) unit with pluggable terminals for convenient wiring
  • 1500V isolation, 4-way (inputs/outputs)
  • Wide ambient operation (-40 to 80°C)
  • Approvals: CE compliant. UL/cUL Class I Div 2, ATEX/IECEx Zone 2
