The Allen-Bradley 1756-OB16DK module is a digital output module for the Allen-Bradley ControlLogix 5580 programmable controller. The 1756-OB16DK module consists of 16 diagnostic outputs, each set of 8 points. The pilot operating current is 2 amps at 30 degrees Celsius and 1 amp at 60 degrees Celsius. The voltage class of the module is 24 volts DC supply voltage. Operating voltage range is 19.2 to 30 V DC. Nominal and maximum output delay times for the turn-off to turn-on process are 60 microseconds and 1 millisecond, respectively. The nominal and maximum output delay times for the on-off process are 630 microseconds and 5 milliseconds, respectively. Current consumption is 250 mA for 5.1 volts DC and 140 ma for 24 volts DC. The module's total backplane power consumption is 4.4 watts. The module has a maximum power consumption of 60 watts at 3.3 degrees Celsius. The 1756-OB16DK module has a heat dissipation of 11.25 BTU per hour.
The 1756-OB16DK module requires a slot in the chassis to install. The housing of the module is open and complies with the T4A North American temperature specification.
The maximum temperature of the air around the module should not exceed 60 degrees Celsius. During storage, the 1756-OB16DK module shall be kept in an environment where the temperature is maintained between -40 and 85 degrees Celsius. The 1756-OB16DK module features a conformal coating that protects against corrosive elements in hazardous locations. The module has a vibration rating of 2 G and a frequency of 10 to 500 Hz. The operating impact rating is 30 G.
