SSR-40DA Solid State Relay
Key Features
- Model: SSR-40DA
- Type: Single-phase solid state relay
- Control Input Voltage: 3-32V DC
- Load Output Voltage: 24-380V AC
- Maximum Load Current: 40A
- Switching Method: Electronic, for fast response and long service life
- Construction: Aluminum heat-dissipating base plate with screw terminals
Replaces / Cross-Reference Part Numbers
- SSR-40DA
- Replaces solid state relays with matching electrical specifications (3-32V DC control, 24-380V AC load, up to 40A)
Compatibility & Fitment
- Suitable for various AC load switching applications including PID temperature controllers, industrial automation, HVAC systems, and motor controls.
- Compatible with microcontrollers and PLCs that provide a 3-32V DC output signal.
- A heat sink is required for loads exceeding 10A to prevent thermal damage and ensure rated performance.
When to Replace
- Relay fails to activate the load when a control signal is present.
- Relay remains stuck in the "ON" position, keeping the load powered without a control signal.
- Unit overheats under normal operating conditions (with an appropriate heat sink).
- Visible damage, such as a cracked housing or corroded terminals.
Installation Tips
- Disconnect all power sources before installation or servicing.
- Mount the relay on a correctly sized heat sink, especially when switching loads greater than 10A.
- Apply a thin layer of thermal paste between the relay's metal base and the heat sink for optimal heat transfer.
- Connect control (input) and load (output) wiring to the correct terminals as marked on the device.
- Ensure all wire connections are secure to prevent arcing and overheating.

Post-COVID Sock Hunt: Finally a Win
Size: Medium, Color: (001) Black / Black / White
Ever since COVID, I haven’t been able to find a pair of socks that hold up for more than a few months. Brands like UA, Adidas, and others seem to have cut corners—likely in response to inflation—by downgrading materials and labor rather than raising prices. The result? Socks that wear thin, rip easily, or lose shape fast.
These, however, have been a pleasant surprise. I’ve been wearing them for a few weeks and so far, they’re holding strong. You can tell some cost-saving measures were still made—certain areas feel slightly thinner—but overall, the construction is solid.
A key win: they stay on. These are ankle socks (not “no-shows”), and they hug the ankle securely. That’s a huge plus in a world where most post-COVID no-shows slide off halfway through the day.
We may never get back to the pre-COVID quality standards without paying a premium, but for now, these are a reliable choice.
Ratings:
• No slipping: 10/10
• Price: 7/10
• Durability (so far): No pilling or loose threads — promising start.

Great Quality and Stylish
Size: Large, Color: (001) Black / Black / White
Exactly what I was looking for. I don’t like socks that are no-show that your ankles rub on the shoe. These are taller than that but shorter than socks that go up and over the ankle. They’re comfortable, good quality, and pretty thick. They’re form fitting m, but not compression. I dint like compression socks, and these are tight, but not too tight.
