12V Power-OFF Delay Relay Module Delay Circuit Module
This module is a cyclic delay module, often used in the product life test, aging test automation equipment testing, PLC industrial controls, electronic development arduino robot, is extensively used.
1. Using advanced quality timing chip control and accurate timing performance is far better than the 555 chip;
2. Has anti-film reverse protection diode, better protection module;
3. Relay is turned on and off times individually adjustable potentiometer function;
4. Can be accessed by a large current load (250V ac 10 A or 30V dc 10A);
5. Output relays have normally open, normally closed selection.
When the module is powered up, the relay immediately pull the pull-in time can be adjust by potentiometer 1-200 seconds (or so), the relay automatically enter the end of time is timing relay disconnected state off time can also be potentiometer adjustment 1-200 seconds (or so), the end of the off-time timing, and then into the pull-in state, followed by circulation, only power will stop working.
Relay load capacity:
250V 10A AC the ideal (2500W power exchange)
30V 10A DC (300W ideal power DC)
The practical application of the best power halved to use, beneficial products to prolong life.

Jimmy Maxwell asked where can I get a basic automatic start circuit for a generator from ?
I have a large generator, its converted from 3 phase to single phase, but I need an automatic start circuit for a single phase supply, when the mains fails it starts and automatically changes over to generator supply. The old 3 phase circuit is no good, as it senses phase imbalance and volts loss, which is no good on single phase - I tried linking all inputs, but it still does not start on mains failure. Has anyone a basic relay circuit anywhere ?? Thanks ......
And got the following answer:
So it is not the whole control system you want to replace, just the power failure/recovery detection. I guess it is possible to replace this with a mains failure relay as a simplest approach. Ideally it will detect over-voltage, under-voltage, and no voltage, but with appropriate delays to reduce nuisance starts. The link below looks like something basic. Its output is a changeover contact (form C). A simple circuit could be a contactor with an appropriate 120VAC or 240VAC coil, or a small DC power supply (12 or 24V) that operates a relay with the same DC coil voltage, as long as power is present. It probably needs mains rated contacts. This relay contact will connect to the circuit wherever the old 3 phase mains failure detection connected. The advantage of this small power supply unit is that you can later add battery back-up for a fail buzzer, time delays, threshold settings etc if you wish. There may need to be a similar modification to the part of the auto start system that detects the generator output is valid.
The timing relay circuit work extremely nicely with diverse applications which might be particular to energy distribution and protection. The relays come with wide adjustment ranges having a scale that may be simple to read either in three or four digits based on the model. These timing relay circuit support in escalating the flexibility of the applications, decrease the all round power and maintenance costs. There are relays which are utilised for basic purposes which are available in reputable styles with swift replacement selections. And you will discover models that happen to be applied for industrial applications and heavier duty applications that function on massive loads. These items are made to meet the lifetime industrial control demands of the applications.
Their most recent goods would be the Time counter, Timer Delay, timing relay circuit, Speedy Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and several other folks. The web page presents a detailed description of each and every model in many categories of timing relay circuit couplings and sensors. These items are particularly helpful for high-risk applications. The timing relay circuit are also accessible with attributes like many timing ranges and functions. The corporation is at present trying to find agents and dealers who can promote and sell their factory made goods. They may be constantly on a lookout for building new and more dependable products based on the needs and needs on the industry.
