DeviceNet J/Bs IP20 - I/O Blocks

These Junction Boxes, or I/O Blocks as they are also known, enable a high density of I/O be added to a DeviceNet bus within an enclosure. All these devices have screw terminals and in some models the terminals are removable.

I/O terminals are along the bottom of the units and the bus connections are either on the top terminals or by M12 connector.

DeviceNet™ Passive Junction Boxes IP67  -   I/O Blocks

These passive junction boxes offer a clean solution to multiple drops from the main DeviceNet Bus within an enclosure or control cabinet. All terminals are screw-type in individually removable blocks. The aluminium  housing is rail-mounting. A terminating resistor is also available, part number JRBS-57TR.
