AB | 1788-CN2DN | Interface Module

The 1788-CN2DN is a ControlNet to DeviceNet linking device from Allen-Bradley. This module functions as a bridge device, enabling ControlNet and DeviceNet-enabled devices to communicate and exchange data. Some compatible devices include Allen-Bradley PLC5, SLC 500, CompactLogix, and ControlLogix controllers as well as DeviceNet adapters such as POINT I/O and Flex I/O adapters. It also supports Allen-Bradley’s Series 9000 Photoeye, 855T Stack light, 1792D- VT0D Maxum Block, Bulletin 160 Drive, and other devices that support DeviceNet communication. The 1788-CN2DN operates when wired to a power supply that delivers an output voltage of 18-32 VDC with a nominal supply voltage of 24 VDC. It supports mounting to a zinc-plated, yellow-chrome steel DIN rail and panel. This module comes with a variety of LED status indicators including DeviceNet network Status; DeviceNet I/O status; ControlNet A and ControlNet B network indicator; Module status and linking activity indicator. The 1788-CN2DN is provided with One (1) rotary switch for DeviceNet data rate configuration; and Four (4) DeviceNet node address switches. For ControlNet communication, this module uses an RG6 connector port while for DeviceNet, the recommended cable is 1485C-P1-Cxxx with a wire size of 0.52 mm2 (20 AWG). For establishing power connection, recommended wire size is 0.25…2.5 mm2 (22…14 AWG), solid or stranded copper wire with a minimum insulation rating of 75 °C (167 °F ) or higher and maximum insulation thickness of 1.2 mm (3/64 in.). The 1788-CN2DN has an operating temperature of 0…60 °C (32…140 °F) and a maximum surrounding air temperature requirement of 60 °C (140 °F). The module’s operating shock is 30g for both DIN rail and panel mounting.
