Palmer Wahl DSX500 | Digi-Stem DSX500/540/501 RTD Thermometer, 4–20 mA | -200 to 800 °C
The DSX500 Series (DSX500, DSX540, DSX501) are loop-powered Digi-Stem RTD thermometers with a 4–20 mA transmitter output, covering -200 to 800 °C. They run from customer-supplied 10–36 V DC; the DSX500 brings power and signal through a 1/2 in NPT female conduit port, while the DSX501 uses a waterproof 4-pin Turck connector. Output scaling is set at the factory or by the user with the optional DSTCAL software. The DSX540 adds a stainless H frame. Probes are sold separately.
