This manual introduces the basic parameters, technical indicators, external dimensions, installation form and selection of SFGW series rail-mounted temperature transmitters.
The SFGW series rail‑mounted temperature transmitter converts thermocouple or RTD signals into a linear 4‑20 mA DC output, offering isolation between input, output, and power to improve system reliability. The device includes features such as cold‑junction compensation, high insulation resistance, and a compact mounting design.
The manual lists technical parameters, wiring diagrams, physical dimensions (24 × 98 × 100 mm), installation procedures for the support‑type rail (TS35), and maintenance recommendations. Warranty information and optional load‑capacity specifications are also covered. This manual is written in Chinese.
| Input signal | Thermocouple or RTD |
|---|---|
| Output signal | 4‑20 mA |
| Output resistance | 250 Ω (1‑5 V output) |
| Load resistance | >500 kΩ (4‑20 mA output) |
| Accuracy (RTD) | ±0.3 % FS (0‑50 °C) |
| Accuracy (Thermocouple) | ±0.3 % FS (range 5 mV) |
| Power supply voltage | 24 V DC ±10 % |
| Power consumption | <1.5 W |
| Operating temperature | 0‑50 °C, RH <85 % |
It accepts either thermocouple or RTD (thermoresistance) signals.
The standard output current range is 4‑20 mA.
A 24 V DC supply with a tolerance of ±10 % is required.
The device has a free warranty for 18 months; after that, service is charged.
