Humidity range: ≤95% RH (non-condensing environment)

Protection level: module protection level IP20, needs to be installed in a control cabinet

Signal processing accuracy: Analog input resolution 16 bits, accuracy ±0.1% F.S.

Accuracy Time Tagging: ABB 83SR50C-E supports high accuracy time tagging capabilities. It can be particularly useful in systems where there is a need for accurate time stamping of events, like in industrial monitoring and control applications.

Defined Outputs at Communication Errors:The ABB 83SR50C-E has defined outputs in case of communication errors. This is a critical safety and diagnostic function.  ABB 83SR50C-E generates signals or sets the output to a defined state if data transfer in the system is interrupted. This permits operators or monitoring systems to promptly detect that a communication issue took place and determine the necessary correcting measures such as investigating the communication wires or network configurations, or ensuring other communicating devices are operational.

I/O Modules with Intrinsic Safety Interfaces:The standard configuration of  ABB 83SR50C-E supports the I/O modules with intrinsic safety interface, making periodic device maintenance much easier. Secret safety restricts the electric power within the module and the associated circuits to a point where it will not ignite combustible gases, aerosols, or dust. 

Overcurrent Protection: ABB 83SR50C-E features overcurrent protection, one of its primary functions, that protects circuits from overcurrent conditions. It is designed to trip, i.e., open in the event the current rating is exceeded, to save other components.

Power Distribution: ABB 83SR50C-E, protects the distribution system in substations, electrical boards and switchgear to help maintain seamless operation.

Industrial Automation:ABB 83SR50C-E is used in factories and manufacture plants for protection of machinery, motors and other electrical equipment.

Energy Generation and Transmission: It is also used to prevent overloads, short circuits and other dangerous faults in power plants and energy transmission systems.

HVAC systems: It is typically used in Heating Ventilation And Air conditioning system to ensure that electric appliances can be safely run.

Solar Power Systems: Track record with industrial protocols, the ABB 83SR50C-E is now widely used in solar power and wind power generation systems to monitor and isolate the electrical circuits.
