FGS-224 wiring to a 24 ac motor

[Roobrother 0]

I have purchased  FGS-224 without reading the fine print and I was hoping someone can assist me.

 

• Always use the same power source for L and IN terminals
• Dry contact - No current:

The 24v ac motor is a HVAC damper ( open/close)

 

I was hoping to power the FGS-224 with say 240v ac pin L and Pin N

then connect the active of a 24v ac transformer to pin IN 

S1 to 24v ac motor ( to close damper) 

S2 to 24v ac motor ( to open damper)

 

The damper motor has three wires Com/open/closed

 

Do you believe this will work or will I need another external relay

 

Thank you in advance

• Always use the same power source for L and IN terminals,

 

I understand this information to be a safety warning due to the fact that you will have two different power supplies on the device. And because people don't remember after a while that they have 230V in addition to 24V, they can get electrocuted.

However, from an electrical point of view, the contacts are separate from the power supply part. So if you use 24VAC on IN, you will also get 24VAC when connected to Q1/2. From the point of view of safety, I recommend using a 24VDC source for powering the module.

 

And the question of use. Your damper has a 3-point control. That is, when the control is switched on one wire, the motor runs in one direction (the damper is braked). When the second wire is connected, the flap opens.
When it is not connected, the damper is stationary.
Secure the blocking so that it cannot lead to the simultaneous switching of both outputs!

Thanks for getting back to me

That is what I was hoping for...DC I get... AC not so much being alternate current

 

I was thinking of a) 2 x 240ac transformers with 1 connected to Q1 -to open damper and the second to Q2 to close the damper..b) a relay 240ac switching 24vac out

Option a) was more costs and option b) Just cannot find in Australia just the 240vac to 24v dc And I was also looking at option c)

as this is powered by 24v ac  and of course switches 24v ac

 

But nice to know FGS-224 will work

parameter 164

Parameter available only in Double Smart Module

When the lock is enabled, both outputs cannot be turned on at the same time.

 

Thank you again @Martin_N for confirming..muchly appreciated

@Martin_N

You are correct..

All working using, as per your advice, 24v dc to power the device and 24v ac to control my HVAC damper.

 

So thank you again...

 

ps anyone trying to add these devices to homeseer HS4...add via unsecure and you will get the two separate relays/switches. Not via S0 or S2
