SLC Safety Relay SLC-3A1B24N Safety Relay

■Features:

● Applicable to safety light curtain.

●Safety relay operated by DC24V power supply.

●Dual-channel operation mode, NPN input, reset switchis provided with contact.

●3 sets of normally open safety contacts output inseries, 1 set of normally closed auxiliary contacts output in parallel.

●With power indicator and channel 1 and channel 2status indicators.

●The number of safety contacts can be increased bymeans of an expansion module.

●Circuits with self-monitoring redundant circuits.

● The safety function of the relay can beautomatically detected by correct opening and closing during each switchingcycle.

●Safety level up to 4, the safety function remainsactive even if one of the components is damaged.

●Connected with the safety light curtain sensor, theoperating status of the safety light curtain sensor and the controlledequipment can be monitored at all times, constituting a safer protectionsystem.

●22.5mm wide, GIN rail mounting.

●Conforms to standards EN60947-5-1, EN61000-6-2,EN61000-6-3, EN60204-1, ENISO13849-1.
