Poweroff memory capability Stores and retains configurations even when power is removed, ensuring consistent operation after power is restored. No reconfiguration needed after interruptions. Cycle control feature Programmable on/off cycles enable precise timing for automated systems. Simplifies scheduling and improves repeatability without extra external logic. Antiinterference technology Optical coupler isolation improves signal integrity and reliability in environments with electrical noise or fluctuating conditions. Enhances performance in challenging setups. Key attributes Function: Nonvolatile memory of settings, programmable cycling, and isolated signaling for reliable control. Compatibility: Designed to integrate with standard relaybased control systems and automation setups. Performance: Stable operation after power loss, timing sequences removed, and strong noise immunity through optical isolation. Applications and use scenarios Industrial automation: Relay modules and control panels that require nonvolatile settings and precise timing for manufacturing lines. Data acquisition and test equipment: Systems that need repeatable, timed control cycles and robust isolation in noisy environments. Building and home automation: Control circuits where settings must persist after outages and where electrical noise is present.
