Crydom HD Series Solid State Relay, Panel Mount, 90A, 530V Load, 32V Control HD4890-10

The Crydom HD Series HD4890-10 is a robust, industrial-grade solid state relay engineered for panel mounting in high-demand electrical environments. Designed to operate reliably with no moving parts, it delivers rapid on-off changeovers below 30ms, making it ideal for systems requiring fast response and minimal wear.

With a maximum load current of 90A and load voltage of up to 530V, this relay is suitable for powering heavy machinery in automation, production lines, wind turbines, and food and beverage facilities. Its control circuit supports voltages between 4V and 32V DC, providing integration flexibility for a wide range of industrial controllers and PLCs.

Zero voltage switching substantially reduces electrical noise and transient effects, protecting sensitive electronics and extending equipment lifetime. The solid-state SCR output enables consistent operation under challenging conditions.

The relay is housed in a flame-retardant enclosure rated IP20 for touch safety and protection against ingress of objects larger than 12mm, making it appropriate for use in environments where operator safety and equipment durability are paramount.

Installation is simplified with screw terminal interfaces, accommodating wire sizes from 24 to 8 AWG. Anti-rotation barriers within the housing keep the relay securely in place during panel mounting, even in vibration-prone machinery.

This relay features an SPST (Single Pole Single Throw) contact configuration, suitable for basic on-off switching tasks. Off-state leakage current is limited to 1mA RMS, reducing standby power consumption. Panel dimensions are compact: 58.4mm length, 22mm width, and 23mm height for easy integration into control cabinets.

The HD4890-10 operates in extreme temperatures from -40°C to 80°C and complies with CE and RoHS standards for environmental and safety assurance. Additional certifications include UL, C-UL recognition, and VDE approvals, supporting use in global industrial settings.
