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

I found this unit did exactly what it was described to do. My application needs to flash a strobe every 15 seconds. This unit is just right for this task. I set it to go on for 1 second every 15. One of my requirements is low power consumption. The seller did a good job discribing the power usage and through testing it was spot on. It uses 12ma to count down the 15 seconds then spikes to 50ma for the one second on. This is due to the solenoid closing the contacts for that one second. After the one second the contacts release and it goes back to 4ma. The click of the contacts is loud and the display is bright but those were secondary and thus 5 stars. Another item to note is that if your Vcc running the timer goes down to just abouve 3 volts DC, the unit goes into convulsions. The display flickers and the solenoids do not close. This does not mean it is any less quality but you should have a solid 12 volts. Pros: Unit is easy to set. Display makes it easy. Uses low power in count down mode. Wire connection points are clearly labeled and tighten nicely with a small screw driver. Programming stays in unit even after the power is shut off. Con: Loud Display cannot be turned off Instructions did not come with the unit but were sent to me later. I had already downloaded them.

Been in place for over a year now and it’s still working as expected

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.

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 confused Timer Easy Setting Instructions The 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 - seconds Top display=P0 bottom display=1 - minutes Top display=P0 bottom display=2 - hours There 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

First of all, they claim to have 18 programs, but they actually have 6 programs that can be executed in time units of seconds, minutes, or hours. They also force uniformity in terms of the time parameter - EVERYTHING is seconds, or everything in minutes, or everything in hours. I have an app where I want to close a relay for 1/2 second every 24 hours. Not possible with this tool. My fault. I should have read the other review before making this purchase.

Once you learn to program it's great! Instructions SUCK! The youtube videos aren't much better, but I must have reprogrammed this unit a hundred times before I got it to operate on mode 4. If you are good at figuring things out and stubborn like me - it will work. I use this for a circulation pump in my 300-gallon water storage unit. It is set to run every 4 hours; to keep the water fresh and stop it from freezing. It is powered by solar and attached to a motor speed control unit.

I read some of the reviews for this product saying that it had to be manually started and that it did not "remember" its settings across power outages, but I was willing to take a chance on a project that didn't matter about things like that. Either the reviewers were wrong, or the design has been changed over time, because this timer delivered! Not only does it start its programmed timing cycle immediately on power-up, but it also remembers its settings even when the power is removed for days. What more could I want? The display is very bright, making it easy to read even outdoors. The contacts are true dry relay contacts, so the timing circuit and the controlled circuit are completely independent. The user manual is linked on the Amazon page, but you have to look for it. It's there. There are a ton of features and modes to chose from, so you'll find a mode that works for what you want. One downside, stated by other reviewers as well, is that the timing units for both timers are always the same. Hours, Minutes or Seconds. You cannot run a device for 20 seconds every 24 hours, but you can run a device for 20 seconds every 900 seconds. If this works for your application, then this is the perfect timer!

With the holiday season just ramping up, I wanted an easy solution to turn my tree lights off after a pre-determined period of time. I found this module and couldn't be happier with it. It's simple to use - instructions are readily available by scanning a barcode that's included in the packaging. I appreciate the step taken to reduce waste - I rarely read manuals and they end up straight in the garbage. I purchased the 24V operating voltage version as I had 24V readily available from an existing adapter. Wiring it up was a painless task and I've been testing my setup the past week. I found the product to be reliable, and will be 3D printing a case for it. This module will allow me to enjoy my lighted tree in the evening and it'll turn off right on schedule. Would highly recommend for anybody.

Easy to program
