Dual SSR Relay Board (3053_0)

The Dual SSR Relay Board (3053_0) provides high-speed, wear-free solid-state switching for two independent AC or DC electrical loads driven by digital outputs.

Unlike mechanical relays, Solid State Relays (SSRs) operate without moving parts, eliminating contact wear, arcing, and audible noise. Built for safety, optical isolation using GaAs LEDs and optically-controlled MOSFETs isolates control inputs from power outputs, protecting connected microprocessors and host systems. Additionally, onboard 47V bidirectional transorbs across the relay outputs shield against static discharge and inductive kickback surges.

Features:

• Controls 2 independent Solid State Relay (SSR) channels using standard digital outputs
• Switches AC loads up to 28V AC RMS / 9A or DC loads up to 40V DC / 9A
• Optically isolated inputs protect control microcontrollers and host devices
• Integrated 47V bidirectional transorb surge protection against inductive loads and ESD
• Silent operation with no mechanical contacts to wear out over time
