Technical Specifications

Detailed engineering parameters based on manufacturer documentation

Parameter	Value	Parameter	Value
Notes on operation	Do not connect adjacent channels to SELV/ PELV and voltages dangerous to the touch.	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 operation	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.	Notes on operation	At least one functional insulation against adjacent modules is complied with in the support rail direction.
Notes on operation	Do not use to separate SELV/PELV circuits from other circuits, because safe isolation is not guaranteed. (applies to the optocoupler variants)	Product type	Relay socket
