Core Functions Multi-Channel Relay Output: Provides 16 independent SPST (Single-Pole Single-Throw) normally-open relay outputs for controlling external loads or driving actuators. High Electrical Isolation: Offers high-level galvanic isolation between channels and between channels and the backplane, effectively suppressing interference and protecting the core control system. Real-Time Status Indication: Each channel is equipped with an independent LED indicator to clearly show the output ON/OFF status, facilitating on-site diagnosis. Safe & Reliable Protection: Utilizes high-specification contact materials with excellent arc and corrosion resistance, supporting long-life and high-load cycle operation. Fast Response: Extremely short signal response time ensures real-time execution of control commands, meeting high-speed and high-precision control requirements. 3.
