Dual Channel RTD converter and Dual Channel Resistance converter
DAT4532B
The DAT4532B Dual-Channel RTD / Resistance Converter is a high-performance, DIN rail mount, isolated signal conditioner for precise temperature and resistance measurement on two independent channels. It accepts a wide range of RTDs — Pt100, Pt500, Pt1000, Ni100, Ni1000 — as well as resistance inputs up to 2000 Ω, and provides temperature-linearized analog outputs in current or voltage format.
Each channel is independently configurable and features full galvanic isolation between input, output, and power supply — as well as channel-to-channel isolation — to eliminate ground loops and ensure signal integrity in multi-sensor systems. Typical outputs include 4–20 mA or 0–10 V, selectable to match PLC/DAQ requirements.
Configuration can be performed via PC software for fast, precise setup or via DIP switches for field adjustability. As the dual version of the DAT4531B, the DAT4532B reduces DIN rail space and cost per channel while maintaining accuracy, stability, and safety.
