Bosch FLM-420-RHV-S High-Voltage Relay Interface Module, 2-Output Surface-mounted
Product Code: FLM-420-RHV-S
FLM-420-RHV-S is a dual-relay interface module that switches 230 V powered loads according to fire scenario. The relays can be set to standard switching or fan control function; since power is supplied from the LSN line, no separate power cable is required. The status indicator can be disabled via software if desired. Surface-mounted switching of high-voltage fans and similar loads eliminates the need to install a separate control panel in the field.
