Acromag TT335-0700 USB Programmable Thin Temperature Transmitter

The TT335-0700 is a USB-configurable, isolated four‑wire transmitter from Acromag that converts RTD or resistance sensors into a proportional DC signal for process control. It accepts selectable input types including Pt RTD (100, 200, 500, or 1000 Ω with α = 0.00385 for 100 Ω), Ni RTD 120 Ω, Cu RTD 10 Ω, or a 0–450 Ω resistance, with a default configuration of 100 Ω Pt RTD (-200 to 850 °C) and a 4–20 mA output offering adjustable filtering. Output options are universal, with ranges up to ±21 mA or ±10.5 V DC without rewiring; voltage outputs require a minimum load of 1 kΩ and current outputs operate over 0–525 Ω, while power can be supplied from 12–32 V DC (local/bus) and the unit supports isolation of 1500 V among input, output, and power. The TT335-0700 features pluggable terminals for easy wiring, supports two-, three-, or four-wire sensor connections, and offers USB v1.1/2.0 configuration via Windows software or Acromag’s Agility Mobile App, making calibration and setup fast and reliable. Dimensions are 4.51 × 0.5 × 3.9 in, and the unit weighs about 8 oz; it is designed for harsh environments with robust shock and vibration resistance and a wide operating temperature range for industrial use.
