The 1794-OB16P is a FLEX I/O Digital DC Output Module by Allen-Bradley and Rockwell Automation. It has an on-state voltage output minimum of 10 Volts DC and includes 16 current, sinking outputs. Additional specifications include an on-state nominal output voltage of 24 Volts DC and an on-state maximum output voltage of 31.2 Volts DC. The 1794-OB16P has an output current rating of 8.0 Amps (16 outputs at 0.5 Amps). Minimum on-state current output is 1.0 milliAmps per channel while maximum on-state current output is 500 milliAmps per channel; maximum on-state voltage drop is 0.5 Volts DC. Surge current for the 1794-OB16P is rated at 2 Amps for 50 milliseconds and is repeatable every 2 seconds while maximum off-state leakage current is 0.5 milliAmps. This hardware has a 50 Volt continuous isolation voltage with basic insulation type.

Output signal delay from off-to-on is 0.5 milliseconds and 1.0 milliseconds for on-to-off. The 1794-OB16P has a FlexBus current of 80 milliAmps at 5 Volts DC and a maximum thermal dissipation of 18.1 British Thermal Units (BTU) per hour at 31.2 Volts DC. It should be noted that the module outputs for the 1794-OB16P are not fused, although fusing is recommended. If you decide to fuse the module outputs, external fusing must be supplied using SAN-0 MQ4-800 milliAmp fuses. General specifications for the 1794-OB16P include an approximate weight of 74 grams, or 2.61 ounces. This hardware comes standard with 16 yellow status indicators; nominal external DC power supply voltage for the module is 24 Volts DC.
