8 Channel Solid State Relay Module (CE05343)

This is a placeholder topic for “8 Channel Solid State Relay Module” comments.



This breakout module gives you access to a 8 channel solid state relay that can be switched with 3-5VDC

Can you please Datasheet for your 8-channel relay board SKU CE05343 - I cant see any on the product information.

Thankyou.

Hey Scott,

I’ll put that in our to-do list and we’ll get onto that for you when someone from the team is able to fix it. Have a great day!

Any update on this? Is this certified in auatralia to connect mains into it? Thanks

Hi Daniel,

At this point in time there’s no legal certification that we supply to confirm its compatibility. That would need to be discussed with the OEM directly. Otherwise, I can confirm that the solid-state relays being used are OMRON G3MB-202P 30Y4E and that the team is working on finding some English references to their specifications. But there should be some information here if the link is still functional.

Can anyone advise whether this relay would be suitable for 24VAC loads (watering system solenoids)?

I have 8 sprinkler zones that I’m looking to control with a RPi, and I’m hoping this module will be suitable. I’ve written the code, I’ve done the plumbing…now for the electronics. I’ve pretty much copied an example I found at https://www.instructables.com/id/Raspberry-Pi-Controlled-Irrigation-System/, leaving out a few of the extra LEDs.

Hi Andrew,

Unfortunately, this particular relay is not suitable as they’re rated to a required output of 100-240 V as listed on the datasheet below.

That being said, there’s another relay available that I’ve also added to this forum post that should be suitable for your particular project, please note that this is a mechanical relay, as oppose to solid state, so it will wear more quickly under frequent use.

If there’s anything else that I can do for you please let me know.

Hi Bryce,

Thanks for your assistance, I haven’t touched electronics since high school, so this is a real learning experience. I had seen the g3mb-ssr-datasheet.pdf but thought the 100-240 V was a maximum. Looking at the both data sheets I can see lots of maximums listed, but which graph or figure did you look at to determine the minimum, i.e. that it’d be suitable for my project (especially in the G5LE datasheet)?

Regards,
Andrew

Hi Andrew,

The G3MB is a solid state relay, the control (input) side is rated for low voltage DC but the load (output) side is rated for 100V-240V AC. Quite simply, 100V is much higher than the 24V AC you need it to work with.

Omron have some good information on using SSRs here: https://omronfs.omron.com/en_US/ecb/products/pdf/precautions_ssr.pdf (See Load Power Supply, 3. Low AC Voltage Loads)

The G5LE is a mechanical relay, so these don’t tend to have minimum AC voltages. Note that the switching current graph for the G5LE goes all the way down to 0 volts.

For anyone else reading, but thinking about working on 240V AC: please keep in mind that it is illegal in Australia for an unlicensed person to perform work on mains wiring (and all mains electrical work must comply with AS/NZS 3000 - The Wiring Rules). Not following standards can be deadly for the next person to work on it (no one’s around forever), or yourself.

Hi,



Could You please advise me on what software controls and switches relays? Also what is max amps that relays can switch?

Hi Jason,

Welcome to the forum! :partying_face: It’ll depend on the relay, usually, they’re either 5A or 10A but it should be listed on their spec sheets or on the relay itself, we can check for you if you’d like to link it here (if you can’t add links you can type the SKU from our page). As for the software to control the relay, you can use anything that you’d like on any microcontroller with the appropriate voltage output to drive them. Most projects run on Raspberry Pi or Arduino boards, but anything with GPIO in the right rating should do the trick. Make sure to let us know if you have any further questions. I’ve linked a tutorial below that you may be interested in regarding this topic. Have a Merry Christmas!
