Teledyne Industrial DH24D25 Solid State Relay

The Teledyne Industrial DH24D25 Solid State Relay is a panel-mount device that switches AC loads up to 25 A from a 3–32 VDC control signal, with a load voltage range of 12–280 VAC and up to 510 V peak blocking. It provides a 1 Form A (SPST-NO) output with zero-cross turn-on and an optically isolated solid-state thyristor output, making it well suited for PLC control panels, packaging machinery, HVAC equipment, industrial heaters, motor controls, and other OEM automation systems that require reliable AC load switching from a low-voltage DC input. The input requires 3–32 VDC with about 10 mA drive current (10 mA, 32 VDC input); the device uses screw terminals (4-Pin) for easy panel connections and is designed for panel mounting. Operable from -40°C to +80°C, it features IP20 housing with reverse voltage and overvoltage protection to support maintenance and retrofit applications in process control, industrial heating, and factory automation, and is commonly used by system integrators for repair, retrofit, replacement, and preventive maintenance of industrial equipment. Common replacements include Teledyne Industrial DRS24D25, S24D25, and SQ24D25 for OEM replacement, repair, retrofit, and preventive maintenance.
