ICSTATION Delay Relay Module, AC 85V-265V Time Delay Switch 0-999s/min/h Timer Relay LED Display Digital Timer Cycle Delay 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 gets easier with use. Cycles accurately. Module has memory... after setting for testing, powering-down, 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. It is unfortunate that the output voltage is never given in the item description, the specs or the manual. Recently have run two in tandem and the timing is very precise, still buy his timer. WOULD LIKE IT IN A BLACK BEZEL (rather than the periwinkle blue, just sayin) My Timer-Defaults: P0=2 P1=5 P2=0 [on 12 hrs then off 12 hrs], Display stays on.

This is a nice digital time module. You can adjust the brightness of the LED digits, but not the out load indicator. I like that the input voltage is anything from 85VAC to 265VAC Set it to cycle and the on time for 12 hours and the off time for 12 hours and you could use it to turn on and off your water heater only during the day. While you are adjusting the times you can hold down the arrow buttons to set the time faster. You cannot adjust the time while it is running the cycle but the accuracy of the timing is very good. This timer has real NXP and ST Integrated Circuits so the quality is very good. there are Three non populated headers on the board. One is connected to the timers internal 5V DC power supply. The second is labelled NTC which means that there may be a version of this module that can monitor a temperature probe The third has traces to what appear to be a non populated optocoupler so I am not really sure what that would have been used for. You can use the Start/Stop button to pause the cycle and then continue the cycle. This is very useful if you are just checking the progress of a process and need to pause and resume. This timer does remember the settings between power cycles, but does not remember where the cycle was interrupted, nor does it restart the cycle when the power comes back on. Overall I recommend this if you need one of these. You will not be disappointed.

Bought this to add a timer cycle to a Halloween prop and it works just fine. You need a project box or some type of case because it doesn’t come with a back. I didn’t find that The instructions for wiring and programming to be very clear but with some trial and error and watching YouTube videos on similar items I figured it out. Once you program it it works fine. My only problem with it is that the power button doesn’t turn it off and on it just starts and stops the program cycle. Had I known before hand I would have put a switch in the box as well

This is a great versatile little timer! It has several different cycle modes as described on the user manual, I am using it for continuous on/off cycling. Once the unit is programmed it holds the settings even when power is disconnected. The timer must be started manually for the first cycle when turned on. (it won't start timing by itself if the power goes out and then comes back on again for instance). In my application the timer controls a 120VAC DPDT power contactor relay that runs two outlets, one wired to NC and one to NO so that I can cycle two 11 amp loads from one 15 amp outlet. Edit to add: One somewhat annoying quirk is that it only counts down in the units its programmed to use, i.e. if counting down 5 minutes it will show 5-4-3-2-1-0minutes for instance, but will not show seconds of time unless in the 'seconds' mode. Likewise if counting hours it only shows hours, no minutes or seconds so it limits how well you can tell where it is in the count, or even if its running.

upon delivery I examined the enclosure and the PCB for any certification body logos, like you'd expect on any consumer electronic device sold in the US. The PCB does not have any silkscreen or labeling showing the product has been reviewed. Components such as inrush current limits and noise filtering are missing or not populated. Reading the data sheet leaves little confidence that this device would pass federal regulation for putting electrical noise back onto your home electrical wiring potentially causing interference with your and your communities electronics. If you do choose to use this device, make sure that all of your connections to mains power are fused. Do not wire the control box directly to the wall, as it does not have any built in fault protection and can cause fire or injury if it were to fail. The device itself is functional and works as intended. I would only recommend using the 12V DC Version of this device due to the complete lack of safety features present.

Instructions could be better but I was able to muddle through it with clarification from their email support. They were prompt & helpful. The unit is a relay and does NOT do power distribution per se. VCC & GND are supplied by a 2-wire lamp cord from a wall plug (110v here in the US). This powers the logic & the display, From a separate wall plug one lead goes to S1, the 2nd wire goes to one "leg" of the outbound cord. The 2nd leg of the cord goes to S0 and the unit completes the circuit as it does it's function. I have uploaded a simplified diagram that might be easier for some to follow The time is easily increased up or down with the setting button & arrow keys. Darkroom timers can be 10times the cost of this unit--they are still asking $129 for a GraLab timer. In the video I plugged in a safelight bulb just for demonstration purposes. Plugging in an enlarger it works the same. I was able to make an enclosure out of a recycled black plastic noodle bowl but you could use a cigar box, plastic conduit box etc.

Versatile timing module. I’m using module to control grow lights for Moso Bamboo, but could be useful for any pumping, HVAC, lighting, hydroponic etc. application. Panel mount package is convenient and makes integration into other products/panels a snap. Amazon instructions are good, and programming is quite straightforward once you get the concept. I didn’t figure out LED display illumination (P2 – display brightness) control. Didn’t see any visible change regardless of setting. However, display is bright and easily readable, but seems to go into a power saving more dim setting after a few cycles. This really isn’t an issue and is probably good since once it’s up and running who needs bright red LEDs glowing all the time… The wiring diagrams were a little confusing. Looking at front of module; from right to left, VCC is the 85-265Vac connection point, GND is 85-265 neutral connection and S1/S0 are normally open relay contacts. From diagrams in Amazon listing you can see that neutral can be jumpered to S1 with load tied across Vac and S0 contacts. The relay contact output is useful as it can be used to control virtually anything (AC/DC etc.). Could even be used to control a 220Vac pool pump or chlorinator module by using on board relay to drive a larger relay… If controlling dc, be careful as relay contacts can be easily burned if not properly snubbered. Suggest doing quick Google search to learn about dc relay snubbering/protection before using for dc applications  Nice versatile module – totally recommend!

Can do lot of things but I wanted to start a timer when it received power and have to push a button.
