RDB1513 is a communication temperature and humidity inspection instrument with high reliability, cost-effectiveness, and easy operation. Rundetek has developed this device by combining domestic practical situations and drawing on foreign technical achievements.
The RDB1513 is a temperature and humidity monitoring instrument that can measure up to 31 points via a single RS485 interface. It supports MODBUS RTU communication and offers additional control functions such as alarms, limit control, and PID control. The device operates on 12‑24 VAC or DC power and includes digital output (DO) contacts for external control.
The manual covers safety precautions, installation methods, wiring diagrams, and detailed configuration of RS485 parameters, MODBUS registers, and sensor connections. It also describes the device's technical specifications, including temperature range, humidity range, power consumption, and output specifications. This manual is written in Chinese.
