Main chip: NE555
Delay modue: delay connect module
Working voltage: DC 12V
Adjustable time : 0-10 seconds(counter clockwise adjustment of potentiometer to increase delay time.)
Control voltage: AC 0~250V/max. 10A, DC 0~30V/max.10A
Max load: 2200W
Module size: approx 68mm x 21mm x 18mm/2.67 x 0.86 x 0.7 inchs
Over temperature protection: Automatically turn off the output after over temperature Weight: 16g/pcs
Module performance and features:
1.Turn on the power relay and delay the pull-in. Specifically: after supplying 12v power , the relay will immediately suck and relay output status: Normally open and public disconnect, normally closed and public conduction; wait until the delay is 1-10s (can be adjusted), the release of the relay and at this time, the state of the relay output is:Normally open and public conduction, normally closed and public disconnect; this state will be maintained as long as the module is continuously powered.
2. The delay time is adjustable, (0 ~ 10 seconds)
3. Increase the potentiometer can increase the delay time
4. Increase the capacitance C1 can increase the delay time
5. Possess of input power indicator
6. Possess of relay pull-in indicator
7. can control the AC 220V/10A equipment. (Maximum control device 2000W)
8. Possess of relay freewheeling protection
9. Delay time formula: T=1.1RC. For example: Capacitance 100uf resistance 100K T = 1.1 * 100000 * 0.0001 = 11 seconds
Applications:
Vehicle equipment-delay to prevent car ignition, prevention of high sudden current to burn components and devices.
Package include:

I bought these to install between our sump pump monitors and our alarm system. Our sump pump monitors each have a SPDT relay output on them. I tied these directly into our alarm system so I would receive and audible and text warning if there was an issue with either pump. After initially connecting this up we found out that when the pumps were very active, the controllers would "blip" the relay periodically causing the alarm to respond. The pumps were never showing a fault when this happened. I think it might have something to do with the unit's built in self-test feature, but I am not 100% sure. I connected the relays to the NO output of the sump pump monitors using 12VDC and I connected the relay board outputs to the alarm panel's zone inputs. Now if there is a fault, the monitors need to stay in trouble for a solid 10 seconds before the alarm is notified. So far, I have not seen a single erroneous alert. there are no instructions included with these relays, but they are quite simple to figure out. power them up for 10 seconds and the relay trips. Getting a 3 pack was great since I only needed two, now I have a spare!

Needed a short delay start for a motor.Turning the pot increases the delay.

The module works fine, but there's no instruction manual included, which makes setup harder for first-time users. Also, the product listing says turning the potentiometer counterclockwise increases the delay, but that's incorrect. Turning it clockwise actually increases the delay time. Buyers should be aware of this to avoid confusion.

I made a homemade golf ball return from a 110v solenoid and it worked fine, but I wanted to slow down the return rate, as the solenoid would sometimes trip before the golf ball was fully in the hole. By using this module, to slow down the solenoid's activation by one second, the return piston doesn't activate until the ball is firmly seated in the cup. Everything worked perfectly. All I had to do, was tweak the timing by turning the potentiometer screw, until the timing was just right. Very very happy.

The Amazon description is gibberish. Here’s a real English description.This is a delay timer that operates on 12v DC. After 12vdc power has been applied, the timer delays before energizing the relay. The delay period (The relay is the Single-Pole-Double-Throw (SPDT) relay commonly used on these types of the boards. The 12v coil is 400ohms. When combined with the two LEDs current consumption is ~40mA when the relay is energized.The relay outputs are independent of the 12v input supply, so you could, for example, control a 120VAC appliance or other load not in common with the 12v supply. The specs say the relay is rated for 10A but this is likely optimistic.- The middle relay contact screw terminal is COM (Common).- The Normally Closed (N/C) screw terminal is confusingly labeled “CBâ€.- The Normally Open (N/O) screw terminal is confusingly labeled “CKâ€.When no power is applied, and during the initial delay period, the relay is de-energized; the “COM†relay terminal is connected to the “CB†(Normally Closed) terminal.After 12v power is applied the delay period will start. After the set period expires, the relay will energize and the â€COM†terminal will disconnect from “CB†and connect to the “CK†(Normally Open) terminal. The relay will remain in this state until the 12v input power is removed.That’s it. If you want to delay powering something on for a few seconds then this board is the answer. If you need a longer delay period or more flexibility, look at the programmable timers available on Amazon.
