The 1755-IB24XOB16 module is a digital I/O module manufactured by Allen-Bradley/Rockwell Automation. The module is part of the 1755 I/O module product line and it is one of the parts of the Allen-Bradley GuardPLC industrial controller systems. These systems are used for control, power, and automation applications in various industries. Besides I/O modules and controllers, the system features other components like an output module, a relay output module, an analog combination module, a combination I/O module, and an input module. All of these components are unique for their respective systems and are protected from current overload and other current irregularities.

The 1755-IB24XOB16 digital I/O module comes with 24 inputs and 16 outputs. The unit weighs only 260 grams (0.57 pounds) and it includes certifications from the UL, CE, and C-Tick standards. The module has an operating temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and it can be stored in environments where temperature range is between -40 and 85 degrees Celsius (-40 and 185 degrees Fahrenheit). The 1755-IB24XOB16 module has a nominal input voltage rating of 24 Volts DC and an off-state input voltage rating of 5 Volts DC. The on-state current is 2 milliAmps at 10 Volts and 13 milliAmps at 30 Volts. In addition to that, the off-state current is 1.5 milliAmps at 5 Volts. The module consumes 0.3 Amps of power at 3.3 Volts DC or 0.5 Amps of power at 24 Volts DC. The 1755-IB24XOB16 digital I/O module has an output current of 2 Amps per channel and a maximum 8 Amps per module at a temperature of 30 degrees Celsius. The operating voltage of the 1755-IB24XOB16 module is 24 Volts DC with a possible deviation of -15 to 20%.
