Product Overview
Omega SSR240DC45 Solid State Relays with Heat Sinks, Unused NOS (Qty 2)
Unused, New Old Stock solid state relays mounted on heat sinks. Buyer receives two units as shown. No signs of prior mounting or wiring. Visual inspection only; not electrically tested. Typically ships same business day from Idaho warehouse. Delivery to lower 48 states usually 3-5 business days.
The Omega SSR240DC45 is a high-current AC solid state relay designed for switching resistive and inductive loads using a low-voltage DC control signal.
Product Condition
Unused, New Old Stock. Both relays and heat sinks appear clean with no evidence of installation. Condition based on visual inspection.
Product Overview
Omega solid state relays are widely used in industrial control panels, process equipment, and automation systems where silent operation and long service life are required. The SSR240DC45 supports high-current AC loads while accepting a broad DC control voltage range, making it suitable for PLC-driven and logic-level control environments.

Frequently Asked Questions
Are these relays new?
They are unused, New Old Stock with no signs of prior installation.
Have the relays been tested?
No powered testing has been performed. Condition is based on visual inspection only.
What is included with the purchase?
Two Omega SSR240DC45 solid state relays with attached heat sinks, exactly as shown.
Do these require external heat sinks?
Each relay includes a mounted heat sink. Additional thermal management depends on load and duty cycle.
Can these be driven directly from a PLC?
Yes, provided the PLC output falls within the 3-32 VDC control voltage range.
Solid state relays like these are built for quiet, repetitive work where mechanical contacts would wear out. Their next service life is defined by the control system that puts them back on duty.
