Relay bank from Bristol Light Console

Bank of relays connected to the Light Console.

The relays do the 'on/off' functions (e.g. sending channels to blackout, setting channels to particular groups, up/down commands).
There are also connections at the base of the box where electrical readings could be taken as part of fault-finding.
