The Allen-Bradley 1756-DNB is a DeviceNet bridge module from Rockwell's ControlLogix 1756 range. It connects a ControlLogix chassis to a DeviceNet network at 125 Kbps (500 m), 250 Kbps (250 m) or 500 Kbps (100 m) with up to 64 nodes. It has one open-style 5- or 10-pin DeviceNet linear plug and a USB port (12 Mbps) for temporary local programming, draws 400 mA at 5.1 V DC and 60 mA from the 11…25 V DC DeviceNet supply. It installs in any slot of a 1756 ControlLogix chassis and takes one slot.
