Allen-Bradley 1756-DNB Bridge Scanner Module

Allen-Bradley 1756-DNB is a ControlLogix DeviceNet Bridge/Scanner Module that acts as the DeviceNet master bridging a DeviceNet field network with a Rockwell ControlLogix chassis. It provides a single DeviceNet port and supports up to 63 slave devices, occupying one 1756 backplane slot and mapping I/O data to the controller. The module draws about 400 mA at 5.1 V from the backplane (24 V backplane input draws 0 mA) and supports DeviceNet baud rates of 125, 250, and 500 kbps (software-selectable); it is UL Listed, cULus, CE, and ODVA-conformant. Operating temperature is 0 to 60 C, storage -40 to 85 C, with IP20 protection when installed in an enclosure, and it remains compatible with all Logix5000 controllers (including 1756-L55, L6x, L7x, L8x series).
