Product short description:
  • Dual channels
  • Universal thermocouple, mV input
  • 4-20mA outputs (sink/source)
  • 7-32V DC loop/local

The DT233 model is a dual two-wire transmitter that isolates and converts millivolt or thermocouple sensor inputs to proportional 4-20mA control signals. Power is received from the output loop current.

DT233: Thermocouple / mV Input Two-Wire Dual Transmitter Description

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

The DT233 model is a dual two-wire transmitter that isolates and converts millivolt or thermocouple sensor inputs to proportional 4-20mA control signals.

Power is received from the output loop current. High-voltage isolation separates all input and output circuits from each other.

Isolation protects from surges, reduces noise, and helps eliminate 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.

DT233: Thermocouple / mV 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 thermocouple/millivolt input types: (TC Type J, K, T, R, S, E, B, N, ±100mV, ±1V)
  • 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
