Information About 1788-CN2DN

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.

The Allen-Bradley 1788-CN2DN linking device is a ControlNet to DeviceNet linking device. The ControlNet network typically consists of HMIs, I/O devices, drives, and Logix processors. The DeviceNet network typically consists of photo eyes and RediStations. The 1788-CN2DN linking device can be used with PLC-5 processors, ControlLogix processors, and SLC-500 processors. The 1788-CN2DN linking device can perform 2 main functions which are the configuration/monitoring and closed-loop control functions.

The 1788-CN2DN linking device is rated for 24 Volts DC and 500 milliamps of input. The cable type required for ControlNet connections is the RG6 cable and the cable type required for the DeviceNet connections is the 20 AWG 1485C-P1-Cxxx cable. Solid or stranded copper cable rated for 22 to 14 AWG should be used for power connections. The dimensions of the device are 120 x 200 x 87 millimeters. The 1788-CN2DN linking device is an open-style device and it complies with the T4A North American temperature code and the T4 IEC temperature code. The operating temperature range for the 1788-CN2DN linking device is from 32 to 140 degrees Fahrenheit and the storage temperature range is from -40 to 185 degrees Fahrenheit. The temperature of the air surrounding the 1788-CN2DN linking device should not exceed 140 degrees Fahrenheit. The ESD immunity ratings for the device are 6 kilovolts of contact discharge and 8 kilovolts of air discharge.
