1791D-16B0

The 1791D-16B0 is a 16-sinking input-base module that belongs to Allen-Bradley’s CompactBlock I/O series. It contains I/O circuits and a built-in DeviceNet adapter and power supply. The input per block for this module is maximum of 2 groups of 8 inputs. Its off-stage voltage is 5 Volts while its on-stage voltage ranges from 10 Volts DC to 30 Volts DC at 40 Degrees Celcius. The off-state current for the 1791D-16B0 is 1.5 mA at 5 Volts DC minimum while its on-state current is from 2 mA at 10 Volts DC to 11 mA at 30 Volts DC maximum. Additionally, the current load for 1791D-16B0 is at 200 mA.

The enclosure type of the 1791D-16B0 is IEC IP20. It also has a 5-95% non-condensing relative humidity and 0 to 60 degree Celsius (32 to 140 degree Fahrenheit) operating temperature. Just like other modules under the CompactBlock I/O series, the 1791D-16B0 has a detachable screw-clamp terminal strip too. It also uses DeviceLogix Smart Component Technology. The 1791D-16B0 module also yields 1 byte for every 8 inputs. When an expansion block is attached to it, an extra byte will be returned stating the condition of the expansion block.

This series of CompactBlock I/O modules, specifically the 1791D-16B0, are ideal to use for space-limited applications. They are also compatible with SoftLogix, SLC, or PLC programmable controllers. The values for these modules can be accessed through the statistical tables of the PLC or SLC controllers. The 1791D-16B0 can accommodate multiple voltage quantities from the DeviceNet network. It can also support various sensors and power supplies. This module also helps reduce node commissioning time.
