Product Description

The H3B-RA relay module is a robust industrial control device equipped with 8 digital inputs and 4 relay outputs, supporting direct connectivity for up to 3 peripheral modules. It operates within a 12-24V DC voltage range and functions reliably across -20°C to 70°C. Compatible with RS-485 and Modbus interfaces, the H3B-RA switch excels in automation, energy management, and machinery systems. Its compact design ensures easy integration, while durable construction enhances longevity in harsh environments. Notable features include a 10A switching capacity, 5mm detection range for proximity sensing, and optional 2000mAh backup battery. Though lacking a display, its simplified wiring and high compatibility make the H3BRA module ideal for scalable control setups, albeit limited by basic diagnostic capabilities compared to advanced PLCs.
