Product Description

The SX-A4450 Relay Module is a 24VDC Solid State Relay (SSR) Control Module designed for industrial automation and equipment control systems. It features 4 isolated input channels compatible with DC signals and 4 output channels supporting 4.5A load capacity per channel, enabling direct connection to actuators, heaters, or solenoid valves. The module supports RS-485 communication interface for integration with PLCs or SCADA systems, operating within a wide voltage range of 18-30VDC and temperature range of -20°C to +60°C. Optimized for manufacturing, energy management, and process control applications, its advantages include fast switching, silent operation, and extended service life compared to mechanical relays. The compact design allows seamless stacking with multiple modules, though proper heat dissipation must be maintained for high-current loads. This maintenance-free solution eliminates moving parts while providing reliable overload protection.
