A fault indicating / pacing relay can optionally be ordered. The pacing
output is electrically-isolated by means of an optocoupler with a semicon‐
ductor switch. The second switch is a relay.
The fault indicating /pacing relay can be retrofitted and is operational once
attached to the relay board - refer to the "Operating Instructions for Retro‐
fitting Relays for Beta b".
