Designation / Model Name (RY12DC8/02)
RY = Relay; 12DC = 12 Volt DC Coil; 8 = 8 Amp DC maximum switching current; /02 = Version 02
 

Component Specifications

• RELAY: 
  • OMRON G5LE-14 12VDC relay in the DualTimer12.
  • OMRON G5LE-14 24VDC relay in the DualTimer24.
    
• Specifications can be found at OMRON's European  web site. (If you can't find the specs on OMRONs's site, we have a PDF copy downloaded in December 2005.) Refer especially the Specifications and Engineering Data headings.
  
  Max relay switch contact ratings include:
  => DC: Power - 240 W; voltage - 30 Volt; current - 8 amp.
       At voltages less than 30VDC, the current spec is more limiting than 
       the power spec.
  • Therefore max DC current is 8 amp

  => AC: Power - 1,200VA (apparent power); voltage - 250V;
       current - 10 amp
       At voltages above 120VAC, the power spec is more limiting than 
       the current spec.

  • Therefore  max AC current at 240v AC is 5 amp
  
  

• SPDT - Single Pole Double Throw switch. 

• Relay endurance information can be found in the Specifications. This can be important especially if you are switching high currents.
  

• DIODE: 1 x Rectifier Diode to protect against back EMF when the relay coil depowers 
  • normally 1N4007; Standard Silicon Rectifier Power Diode; 1000v, 1Amp
     
• TERMINAL BLOCK: 5 Way Screw 
  • Normally comprised of 1 x 2 way block for the signal connections to the relay coil, and 1 x 3 way block for the relay contacts
  • 5mm cable size; Rated at 250 v AC, 10 Amp

Manuals
Please read the manuals for your module as they contain important additional information:

• RelayPair12
• RelayPair24
• RelayPair12d (also read the manual for the RelayPair12)
• RelayPair24d (also read the manual for the RelayPair24)

Example Applications
We also provide example application information. This may vary in form. For example:

• an application which uses only one module type may only include setup instructions (eg Door Open Too Long or DOTL alarm using the DualTimer)
• an application which uses more than one unit or unit type may include a circuit diagram (eg simplified "Traffic Lights")

Naturally, example applications are only intended as a general approach to using our modules. It is the users responsibility to use our modules safely, correctly, and appropriately.

CATALOGUE
Our catalogue is available as a PDF document.

Availability and Price
Our modules are available throughout Australia.

Suppliers - Trade and Commercial
We supply a number of companies who sell to trade and are normally able to provide technical and other services as well. Many have interstate offices/warehouses. If you intend purchasing in commercial quantities, we recommend you contact these people.

Suppliers - Retail
We at ULTRAsmart  provide a postal service for non-trade customers who only want to buy in small quantities.  Payment is required in advance.

The above companies selling to Trade may also sell to retail purchasers.

DISCLAIMER
You should check all component specifications yourself, and only use the Relays after taking into account the specifications. 

AC current applications should only be done by licenced electricians.  

If you use our Relays, you do so at your own risk.

ULTRAsmart, its employees, directors, owners, shareholders, contractors cannot be held liable for any damage resulting from the use or misuse of these Accessories. Thoroughly test before implementing any applications using these Relays.
