PHOENIX CONTACT

20 Pcs.

Safety relay with forced conduction contacts according to DIN EN 61810-3, contact switching type 2 switches. The requirements for type A according to DIN EN 61810-3 are met if the connection is made as 1 normally open contact/1 normally closed contact. Safety relay with force-guided contacts in accordance with DIN EN 61810-3, contact switching type: 2 changeover contacts. The requirements for type A in accordance with DIN EN 61810-3 are satisfied if the circuit is designed as 1 N/O contact / 1 N/C contact.

Technical data
Notes
GeneralThe outputs are not suitable for switching different outer conductors.
GeneralAt least a basic level of insulation is maintained against adjacent modules in the DIN rail direction. If the application has higher requirements on the insulation (reinforced insulation), then these must be realized through suitable measures (e.g. partition plates).
