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.

So versatile! Perfect solution for dividing a room.
Size: 4 Panel-88'', Color: Grey, Size: 4 Panel-88'', Color: Grey
Perfect solution for my space. My office has to double as the hangout room for the kids and I wanted something that would block off my computer so it is left alone. This space allows me to close off my computer as much or as little as I want. It is lightweight yet has sturdy feet. This is important so that if it gets bumped it won’t topple over. The price was great and the build time wasn’t too bad! I would recommend two people for set up. I went with the grey panels and I think I’ll end up hanging some twinkle lights at some point. Great purchase!

4/5 Stars
Size: 4 Panel-88'', Color: Black
Very tall and easy to set up, the only thing I will say is that they do have large gaps in between, so you won't have 100% privacy unless you add a curtain in the back. Other than that, they are easy to fold, sturdy, and esy to assemble. The gaps are an easy fix so I would say they are worth it.

Great product and worth the money.
Size: 4 Panel-88'', Color: Black
Portable and stable. Perfect size and gives me the privacy I need when working from home. Stability is great as long as you place the stands correctly it won't wobble. I love it.

Attractive
Size: 4 Panel-88'', Color: Grey
The assembled product is just as described. The screens look great! I am using them to hide the cluttered shelving in my garage. The area now looks quite neat Something I must say, though, is that the assembly was extremely difficult. I had to use a silicone spray and some pounding to get the A and B poles to fit together. Also, it required a great deal of strength to stretch and hold the fabric panels so that the bars inserted in each hem lines up with the screws inserted in A/B poles. I strongly recommend having a partner to help with the assembly.
while sc and screw into poles them once inserted intetchedtne end of each pole ( and B poles barely fit together. I used silicone spray on the end and then pounded them

It’s beige and not white. Once install - hard to disinstall. Need a drill to put it together
