Siemens LFS1 flame switch is designed to operate with a PLC. When the PLC is the combustion safeguard powering the shutoff valves, conducting burner sequencing, monitoring interlocks, and controlling purge, the LFS1 flame switch signals flame presence to the PLC via a contact closure. The compact design of the LFS1 saves premium panel space. The LFS1 carries global approvals including SIL3 capable.
