Product Description

The SZ-AXRK4 controller is a versatile industrial automation device equipped with 4 analog/digital inputs and 2 relay outputs, designed to directly interface with up to 6 SZ series relay modules for scalable control solutions. It integrates the AXRK4 temperature sensor for high-accuracy thermal monitoring (±0.5°C) with a non-contact detection range of 0.1-5 meters. Supporting RS-485 and Modbus RTU protocols, this controller operates within 12-24V DC and withstands industrial temperatures from -20°C to 70°C. Ideal for HVAC, manufacturing, and energy systems, it features a compact 3.5-inch display for real-time data visualization. Advantages include ruggedized IP54-rated housing and low power consumption, though lacks built-in Wi-Fi. Compatible with lithium backup modules (optional) for uninterrupted operation.
