D2440D-10 Dual Solid State Relay Random Turn On SSR 4 15 VDC Input 280VAC 40A

This Dual Solid State Relay is a random turn on SSR with a 4-15VDC input, 280VAC output, and 40A rating.

Product Overview

This Dual Solid State Relay (model D2440D-10) is a random turn on SSR designed for switching AC loads with a DC control signal. It provides reliable, silent switching for industrial and commercial applications requiring 40A at 280VAC. This dual solid state relay is ideal for high-cycle applications where mechanical relays would wear out quickly.

Key Features & Performance

• Dual relay configuration for switching two independent circuits
• Random turn on switching for precise phase control

Frequently Asked Questions

Q: What does random turn on mean for this SSR? A: Random turn on means the relay switches on at any point in the AC waveform, allowing for phase-angle control and reduced inrush current in certain loads.

Q: Can this relay be used to switch resistive loads like heaters? A: Yes, this SSR is suitable for resistive loads such as heaters, as well as inductive loads like motors, provided the current does not exceed 40A.
