Light Curtain Safety Relay

Light curtain Safety Relay supports PNP-type light beam devices. Safety relay modules provide a high level of fail-safe operation for critical processes and protection. These light curtains and multifunction controllers provide multiple functions such as release delay, muting, stepping, and protection for multiple curtains.

Safety rated relays can choose single or dual channel operation, manual or automatic reset, with function of short circuit monitoring between channels.
