1791P-16B0

|

The Allen-Bradley 1791P-16B0 distributed I/O module has been designed and manufactured as part of the Allen-Bradley/Rockwell Automation CompactBlock I/O 1791P series. It is a standalone type of distributed I/O module rated at 24 Volts DC. The 1791P-16B0 distributed I/O module has 16 I/O channels built into it. It can be stored at -40 to 85 degrees Celsius or -40 to 185 degrees Fahrenheit and it can operate at 0 to 60 degrees Celsius or 32 to 140 degrees Fahrenheit. The 1791P-16B0 distributed I/O module has an IP 20 rated enclosure, and it should be installed in a stronger secondary enclosure for a greater degree of protection.

Product Lifecycle Status*Discontinued/Obsolete

* The Allen Bradley 1791P-16B0 has been discontinued by the manufacturer, however we specialize in obsolete parts and can likely still supply surplus and/or refurbished replacement 1791P-16B0 units instead of migration.

The Allen-Bradley 1791P-16B0 is a CompactBlock module for the PROFIBUS DP with 16 sinking input points that can be grouped together into groups of 4 or 8 in one block. In the on-state, its voltage is a minimum of 10 Volts DC and it is a maximum of either 30V DC at 40 degrees Celsius or of 25 Volts DC at 60 degrees Celsius. Its off-state voltage is a maximum of 5 Volts DC and its current is a minimum of 2 milliamps at 10 Volts DC and it is a maximum of 11 milliamps at 30 Volts DC. The 1791P-16B0 module also comes with status indicators and it can be mounted horizontally or vertically with a panel mount or DIN rail mount. This block I/O provides a grounded connection to the load. The number of inputs per block of this module is varied. Due to this, this module produces 2 bytes and consume 0 bytes. The 1791P-16B0 communicates through a PROFIBUS DP link. Be sure to download configuration files before configuring block I/O. You can download the configuration files on the Allen-Bradley website. The 1791P-16B0 also has several indicators to check the condition of the module, network, and I/O status. Each indicator has its own sign. This module also has both vertical and horizontal mounting.
