Relais SMIS105LM01 is a 4-pin, replaceable relay with a 10 A switching capacity. It uses a DC5V coil and is part of the SMI05V series, identified as the SLA model in the HRMHS line. Key benefits - High current switching: supports loads up to 10 A, enabling reliable control of motors, pumps, lighting, and other devices from a low-voltage control signal. - Replaceable design: simplifies maintenance and reduces downtime by allowing easy field replacement. - Simple 4-pin configuration: straightforward wiring and integration with standard control electronics. - Cross-series compatibility: designed to work within the SMI05V SLA module and the HRMHS line for seamless system integration. - 5V control compatibility: ideal for microcontrollers and automation controllers that provide a DC5V control signal. What it solves - Electrical isolation between control logic and load, protecting sensitive control circuitry. - Higher-load switching in compact form factors, suitable for small to mid-size automation tasks. - Easy maintenance in systems using SMI05V SLA modules and HRMHS components. Use scenarios - Home or building automation: switch a 10 A lighting or fan load from a 5V control signal. - Industrial control panel: replace a failed relay in an SMI05V SLA module within the HRMHS line to restore circuit function. - Prototyping and development: drive a higher-current device (motor, pump, or similar load) from a microcontroller or automation controller with a 5V coil drive.
