The Allen-Bradley 1791D-16B0X is a 16-sinking input expansion module that belongs to the CompactBlock I/O product series. It has an 11 mA at 30 Volts DC input on-state current and 1.5 mA at 5 Volts DC input off-state current. This module also has 16 inputs per block and holds an IEC IP20 enclosure type. It produces 3 bytes for every 16 inputs and consumes 2 bytes for every 16 outputs. The expansion power need for this module is 5 Volts DC (voltage) and 100 mA (current). Its operating temperature ranges from 0 to 60 degrees Celsius.

The CompactBlock I/O expansion modules, including the 1791D-16B0X block, can be added to any CompactBlock I/O base module to expand the I/O assembly up to 32 points. This module is mostly used for in-cabinet applications. It has 14 AWG Stranded connection cables and an isolation rating of 500 Volts AC I/O to DeviceNet. Each of the 1791D CompactBlock I/O modules carries the autobaud feature which allows it to detect the baud network rate upon connection to the live network.

The 1791D-16B0X module can be mounted to a DIN rail or on a panel. This expansion module must be grounded first before installing. Yet, expansion blocks should NEVER be installed or uninstalled when power is put into the base. This may cause a destructive explosion in location installations. In addition, the 1791D-16B0X must be installed in an appropriate enclosure with a genuine wiring method that complies with the part’s electrical codes and regulations. The expansion dimensions for the 1791D-16B0X expansion module are 4.4 X 1.9 X 1.5 inches, and it weighs around 0.1 kilograms (0.3 pounds). Finally, this module has 5 to 95% relative humidity without condensing. This product is also CE marked, meaning that it has been certified for all relevant directives.
