The Autonics SRHL1-1440R 40 A Solid State Relay is designed for AC load control in industrial automation systems. This model supports 40A rated load current, operates across 48–480VAC load voltage, and accepts 10–30VDC input voltage for control signals. It belongs to the SRHL1 Series and is used in panel- or DIN-mounted industrial control assemblies.
In industrial automation environments, the SRHL1-1440R Autonics 40 A Solid State Relay is applied in conveyors, packaging equipment, automated assembly lines, and process control panels. Solid-state switching supports consistent AC load handling without mechanical wear, while panel and DIN rail mounting allow flexible installation. Random turn-on operation enables controlled switching where phase synchronization is not required.
The SRHL1-1440R Autonics 40 A Solid State Relay combines single-phase operation, 40A switching capacity, and high dielectric isolation to meet industrial control requirements. Manufactured under Autonics standards and organized within the SRHL1 Series, this relay is suitable for industrial automation systems requiring reliable AC load control and stable long-term operation.
