What is an Atamate relay

An Atamate relay is a circuit board (PCB), typically consisting of an even number of relays to control circuitry, e.g. open and close ventilation valves, windows or curtains. These boards are designed to fit into either a standard UK electrical ‘backbox’ or a dedicated enclosure.

The relays can have different voltage and current ratings so care should be taken to ensure you meet ratings and safety applications. Common relay sizes are;

  • 1Amp 240Vac/30Vdc, 
  • 7Amps 240Vac/30Vdc
  • 16Amps 250Vac/30Vdc.

What does the Atamate relay do?

The Atamate relay provides a means for the Atamate system to control on/off output devices. Because the output ‘contacts’ are electronically isolated from the control circuitry, it doesn’t matter what the load voltage and current requirements are provided they are less than the relay’s maximum contact ratings.

Many of the relays have change-over contacts, but some only have ‘normally open’ contacts. Atamate relay boards generally use ‘bistable’ relays, so the relay will stay in the ‘set’ or the ‘reset’ position without power unless changing their position. This reduces power consumption and thus the risk of overheating.

The relay will not always return to the ‘reset’ position when the power is removed. The Atamate processor units have a power fail detect circuit which, if required, puts the relay in a predetermined state (usually the ‘reset’ position) before the internal power supply runs out.
