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
  • 4-15VDC input voltage range for compatibility with standard logic signals
  • Rated for 40A continuous current at 280VAC
  • Solid state design with no moving parts for long life and silent operation
  • Optically isolated input for safe signal separation

Technical Specifications

  • Part Number(s): D2440D-10
  • Input Voltage: 4-15VDC
  • Output Voltage: 280VAC
  • Output Current: 40A
  • Switching Type: Random Turn On
  • Relay Type: Dual Solid State Relay

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.

Product appearance and specifications may vary slightly by batch. Compatibility may vary by serial number. Verify fitment before purchase.
