Product Details

Notes on operation Do not use to separate SELV / PELV circuits from other circuits, because safe isolation is not guaranteed.
Notes on operation The outputs are not suitable for switching different outer conductors with appropriate switching output (applies to the AC optocoupler variants and relays).
Notes on safety The system installer must ensure the touch protection of the product (at voltages > 25 V AC/60 V DC). The product is a built-in device without protection against direct contact.
Assembly instruction: At 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).
Assembly instruction: Any unused screw connections have to be tightened with torque.
