PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1791-16B0 is an Input Module belonging to the Block I/O 1791 series. This unit provides 16 DC inputs organized into two groups of eight inputs. The input circuits accept an on-state operating voltage range from 10 V DC to 30 V DC. The nominal input voltage rating for the module is 24V DC.
Input impedance is rated at 3.4 K Ohms for interfacing diverse sensors and switches. On-state current ranges from a minimum of 2.5 mA to a maximum of 11 mA. The maximum off-state voltage is specified at 5 V DC. Integrated status LEDs indicate channel operating states during live operation. Power dissipation reaches 11.1 Watts, generating 38 BTU/hr of thermal dissipation. The unit supports 14 gauge wire connections and weighs 1.00 lbs.
