The 90 A rating is the continuous load current the semiconductor can carry when mounted on an adequate cooling surface — the datasheet explicitly states 'for mounting on available cooling surfaces', meaning the 90 A figure assumes a heatsink sized to the application's duty cycle. Without proper thermal management, the relay will thermally trip or fail. The control input is 24 V DC, which is the standard PLC-level signal voltage across most industrial automation panels. The spring-loaded terminal connection (cage-clamp style) accepts solid or ferruled stranded conductors without requiring a screwdriver torque check — relevant for panel builders who want consistent connection quality across multiple terminations. ## Compliance and regulatory documentation RoHS compliant since 15 January 2024. Export control classifications are AL: N / ECCN: N, meaning no special export licensing is required for most destinations. For audit purposes, the manufacturer provides a declaration of conformity covering the applicable EU directives — this is standard for SIRIUS components and satisfies tender documentation requirements. The 22.5 mm width matches the SIRIUS modular system, so it aligns with adjacent contactors, overloads, and power supplies on the same rail. The spring-loaded terminals face forward for wiring access; strip length for the conductor should follow the manufacturer's recommendation (typically 8-10 mm for this terminal type) to ensure full cage engagement. Because the relay requires an external heatsink for the 90 A rating, the panel layout must allow airflow or direct metal-to-metal contact with a chassis-mounted cooling plate.","metaTitle":"Siemens 3RF3190-2AA04 SIRIUS solid-state relay, 90 A","metaDescription":"Siemens SIRIUS 3RF3190-2AA04 semiconductor relay, 1-pole 22.5 mm, 90 A 48-460 V / 24 V DC spring-loaded terminal.
