3.21 RIM800 RELAY INTERFACE MODULE
3.21.1 GENERAL
The RIM800 Relay Interface Module is suitable for relay outputs which require clean voltage
free contacts and no supervision. For example it can be used to signal states to other
systems (e.g. BMS or security systems), or to energise loads that do not need to be
supervised, e.g. Door Holders.
