Description
The RB1 Relay board converts the Open Collector (O/C) output from the L746 Overdoor Lights and selected LCD Displays, into voltage free ‘Normally Open’ and ‘Normally Closed’ contact sets. The unit is also fitted with a Nominal 12v output derived from the Network voltage, which may be used to drive low current (Max Load 10mA) devices from the network. The unit may also be used to trigger a call point (or similar device) from a DC Voltage input.
