RB1 Relay Board

The RB1 relay board converts the O/C output from the LCD displays and L746 Overdoor light into ‘Normally open’ and ‘Normally closed’ contact sets. The unit may also be configured by the factory to provide time delays for some door applications. It may also be used to trigger a call point from an external voltage (e.g. door bell etc.). The unit is fitter with a ‘T’ 12v output which may be used to drive low current devices from the network.
