Bosch FLM-420-RHV-D High-Voltage Relay Interface Module, 2-Output DIN Rail Type
Product Code: FLM-420-RHV-D
This rail-type module directly controls two 230 V powered circuits via commands from the fire panel. Each relay can operate in standard switching function or be set to fan control function; operating status is monitored by an indicator, which can be muted via the data bus if required. Since the module derives its power from the loop, it requires no separate power terminal in the panel. With dimensions of 110 x 110 x 48 mm, its compact size facilitates installation in crowded panels.
