Functional description
The FLM-420-RLV1 Relay Interface Module Low Voltage has a change-over contact relay to provide a potential free
output contact.
The FLM-420-RLV1-E type in-built can be flush mounted in standard device boxes in accordance with EN 60670;
alternatively, it can be installed in the devices (see Figure 6 to Figure 7, Page 7).
Address setting
Address setting is carried out using the 8 DIP switches and a suitable pointed object (see Figure 1 to Figure 4, Page 4
and the following tables).
Connection
