Timer Relay, Icstation DC 12V Time Delay Switch 10A Timer Switch Module Programmable Digital Time Cycle ON-Off Control 0-999s/min/h LED Display Time Relay Switch Module for Light Water Pump Engine

Excellent! works as described, many timing configurations possible. Programming for timing seems a little confusing at first but them when working with the powered device it is very simple and easy to adjust. Cycles accurately. Module has memory... after setting for testing, unpowering, changing wiring to needed setup and powering back up, the custom settings I had made before were still exactly as set, nice feature! I think this is a brilliant little device for those of us needing a timer relay added to our circuits, works for me.

This timer is able to do many timing tasks since it is programmable. Bright displays make it easy to see in just about any light. Wide range from 1 second to 999 hours. Easy to wire up. The instructions are not very clear at first so I wrote up an instruction sheet that might help if you get confusedTimer Easy Setting InstructionsThe upper display is referred to as (T1 or PV) and the lower display is referred to as (T2 or SV).The LED labeled "out" indicates that the relay contacts are closed when it lights up.Time set mode:Short Press the SET button and use the up and down buttons to set the time in the Top display(T1 or PV) short press the set button to set the time displayed in the bottom display (T2 or SV) short press the set button again to save and run.Time unit setting Mode.You can set the timer to work in seconds, minutes or hours:Long press the SET button for 6 seconds or until P0 is displayed in the top display.Press the up down buttons to set the time unit mode in bottom display (T2 or SV)Top display=P0 bottom display=0 - secondsTop display=P0 bottom display=1 - minutesTop display=P0 bottom display=2 - hoursThere are 5 timer sequence modes:Long press again to set the operating mode when P0 is displayed press set to display P1 then press the up down buttons to display 1 or 2 or 3 or 4 or 5 to set the type of timed operation you want.P1-0 Load is off until (T1 or PV) time counts down to 0 then the load will come on and stay on.P1-1 The load comes on as the power button is pressed. After PV Time the load will go off.P1-2 The load is off for (T1 or PV)(delay time) then the load switches on and runs for the time set in (T2 or SV) then switches off until power switch is pressed to cycle again.P1-3 Load is on until PV Time runs out Then after SV time runs out the load will come on and stay on.P1-4 Load is off until (T1 or PV)(Delay) time counts down to 0, then load comes on until SV time counts down to 0 then the load is off then it cycles again and again-auto cycle.P1-5 The load is on until (T1 or PV) time counts down to 0 then powers down and after (T2 or SV)Time counts down to 0 the load will start working and cycle again and again-auto cycle.Done

This little timer seems like it's pretty good quality. The LED displays are bright. The buttons are firm and you can feel a click when you push them. The terminals feel pretty solid. This is perfect for my application as I needed something that could handle at least 10 amps. This timer is deceptively small but In a good way. I was imagining something just a little bit bigger from the pictures and the dimensions. It does exactly what I needed to do...almost. instructions are a little hard to understand at first but once you mess around with it it's pretty simple to understand. And you can't really mess this up. If you find out you did something wrong you just go back and reprogram everything. Which is a couple pushes of the button.I would love to give this timer five stars but the one problem for me is (and this was probably me not reading the description right) when it says that it has multiple programs it means you can only choose one program to run. I was hoping to be able to switch between programs with the push of one button. That is not the case. You basically program one specific program and run that program. if you need to switch to a different program you have to reprogram everything. I was going to use this as a live well timer and have it set up so that one program ran the initial fill and shuy off. then switch to a second program and have it cycle fresh water for 5 minutes every hour. So now I have it set up to run the initial fill time and then shut off for an hour and keep repeating that cycle.

Works great once you figure out how to program it. I went to the manufacturer website and printed then out. Very simple if you go step by step. Using it to control a vacuum pump on a chamber for degassing epoxy

The programming instructions are not detailed enough. Cannot get to program to power a 12 voltage device for 15 seconds. A waste of my time and money!!!!!!

I have this controlling a 30W water pump for an aeroponics system and it just works. I like things that I don't have to worry about. The bonus is that it remembers the settings after a power failure.Thank you to another reviewer that had a better explanation of the settings.

The product seems ok, BUT I am having such a hard time figuring the thing out!!! I downloaded the manual but still!!I will keep trying to figure it out and do another review.
