Product Description

The PRA12-2DN Pressure Switch is a compact, dual-channel Digital Pressure Sensor designed for high-precision monitoring in industrial automation. It features 2 independent inputs and 2 configurable outputs, supporting direct integration with up to 4 modular expansion units via RS-485 or Modbus RTU protocols. Operating at 12-30V DC and rated for -20°C to 80°C, it excels in harsh environments like oil/gas, water treatment, and HVAC systems. The sensor boasts a 0-100 bar measurement range, ±0.5% F.S. accuracy, and IP67 protection. Its dual-node architecture enables simultaneous monitoring of two pressure points, enhancing system redundancy. A 2.4-inch LCD provides real-time data visualization. While offering robust reliability and easy calibration, its specialized design may require tailored installation in complex setups.
