Celduc SO8 Series Solid State Relay 40A Load, 275 Vrms Load, DIN Rail Mount SO843970

Celduc SO843970 SO8 Series Solid State Relay is engineered for industrial automation requiring reliable switching of AC loads up to 40 Amps at 275 Vrms. Designed for mounting on DIN rails, this single-phase relay employs triac output with zero cross switching functionality to minimize electrical noise and enhance longevity.

The relay features a wide regulated control voltage range from 20V AC/DC up to 265V, providing versatility across multiple applications in manufacturing, HVAC, and control systems. The compact profile (30mm x 44.8mm x 58.5mm) and IP20 rating allow installation in standard electrical panels with robust protection against dust and indirect contact.

Built with screw terminal connections, the device facilitates secure and efficient wiring. The on-state resistance of 16 milliohms ensures minimal power loss during operation, while an off-state leakage current of only 1mA helps maintain system efficiency.

Special features include voltage protection for both input and output lines using transil and voltage-dependent resistors (VDR) respectively, offering high immunity to electromagnetic interference. The relay's green LED input display enables immediate visual feedback on operational status.

Operating temperature ranges from -55°C to 100°C, but thermal management via heatsinks is recommended to sustain maximum current ratings and prevent thermal overload. The relay complies with leading international standards such as EN60947-4-3 and EN60950, ensuring safety and certification adherence.
