Product Description

The R33B series integrates the R33B Temperature Sensor, R33B Control Module, and R33B Sensor Module into a versatile industrial solution. The R33B Temperature Sensor supports up to 4 analog inputs, measures temperatures from -40°C to 125°C with ±0.5°C accuracy, and detects targets within a 5-meter range. The R33B Control Module features 8 configurable I/O ports, operates at 12-24V DC, and links directly to 8 Sensor Modules via RS-485 or Modbus interfaces. Designed for harsh environments, it functions reliably in -20°C to 70°C conditions. The R33B Sensor Module includes a 2.4-inch status display and optional 2000mAh backup battery. Widely used in HVAC, manufacturing, and energy systems, the series offers modular scalability and robust performance but requires periodic calibration. Limited wireless compatibility may necessitate additional adapters for IoT integration.
