JWSL-6 series protection type temperature and humidity transmitter instruction manual, suitable for temperature and humidity measurement of HVAC indoor environment and ventilation pipe
The JWSL-6 series protective temperature and humidity transmitter is designed for HVAC‑level indoor environments and ventilation ducts, offering accurate measurement of temperature and humidity with multiple output options. It supports 4‑20 mA current, 0‑5 V voltage, RS‑485 and RS‑232 network interfaces.
The manual covers technical specifications, physical dimensions, wiring colour codes, installation methods for wall‑mount, pipe‑type and split‑type configurations, operation procedures, safety precautions, maintenance recommendations, troubleshooting tips, and the MODBUS RTU communication protocol. This manual is written in Chinese.
| Power supply | DC 24 V (22 V–26 V) |

| Temperature accuracy | ±0.5 °C (0 °C–50 °C) |
| Working temperature | -10 °C – 60 °C |
| Dimensions | 86 mm × 117 mm × 41 mm |
| Weight (wall‑mount) | ≈ 170 g |
| Weight (pipe‑type) | ≈ 430 g |
| Long‑term stability | Humidity <1 % RH/yr, Temperature <0.1 °C/yr |
| Response time | <15 s at 1 m/s wind speed |
For wall‑mount, align the two φ4 mounting holes on each side of the transmitter with the wall and fix them using the supplied expansion screws; ensure the sensor faces downward.
Red is power +, Yellow is RS‑232 receive (or RS‑485 A+), Blue is RS‑232 transmit (or RS‑485 B‑), and Black is ground.
The network version follows the MODBUS RTU protocol.
