The 1755-HSC module is a high-speed counter module that is designed and manufactured by Allen-Bradley/Rockwell Automation. The module is part of the Allen-Bradley Bulletin 1755 product line and it is compatible with controllers from the Allen-Bradley GuardPLC 2000 series. The module includes two high-speed counters and four digital outputs. The GuardPLC 2000 controllers that this module works with operate on DC voltage and their operating voltages are 3.3 Volts DC or 5 Volts DC. The 1755-HSC module is produced in accordance with requirements from multiple industrial standards including certifications the CE, UL, C-Tick, and Functional Safety by TUV standards.

The 1755-HSC module can have an input voltage of 5 Volts or 24 Volts and it has an input current of less than 3 milliAmps. The input signal frequency of the module is from 0 to 1 megahertz. Besides that, the module has a trigger with falling edge and status indicators for the power supply status, module status, and I/O status. The 1755-HSC module requires shielded and twisted input cables that are equal or less than 500 meters in length and rated for a requency of 100 kilohertz. The 1755-HSC module has a 0.2% accuracy of time basis and resolution of 24 bits with a value range of 0 to 6,777,215. The operating voltage of the unit is 24 Volts DC with a deviation of -15 to 20%. The operating temperature of the module from is 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and its storage temperature should be within the range of -40 to 85 degrees Celsius (-40 to 85 degrees Fahrenheit). The weight of the 1755-HSC module is 260 grams (0.57 pounds).
