HD-WDS Series 2-Wire DC Signal Transmitter - Precision Measurement and Reliable Performance

The HD-WDS model is a 2-wire DC signal transmitter designed for converting various DC signals such as current and voltage into standard instrumentation signals. Operating within a temperature range of -5℃ to +55℃ and a humidity of 90% (non-condensing), it mounts easily on DIN rails. With an input range of -500 to +500V DC, it outputs a 4-20mA DC signal with a load resistance of up to 750Ω. The device features a high accuracy of 0.25% and a fast response time of 0.5 seconds or less, ensuring reliable performance in demanding applications.
