SD113E is a type of safety device used in industrial applications to protect against electrical shock hazards, as well as provide global and local safety diagnostics. The device is capable of monitoring outputs from up to four circuit breakers, offering a broad range of adjustable settings to help suit the user’s needs and application environment.

SD113E\'s application field includes enterprise-level, high volume, and hazardous AC/DC electrical environments that require diagnostic level protection with fewer points of maintenance. The device is particularly well-suited to safety applications that require absolute criticality and must offer very low failure rates. It is commonly used in electrical and process control, machine and machine-tool service, HVAC, and automotive manufacturing.

The SD113E works by combining three safety diagnostics in a single integrated unit, providing complete local and global protection. The first safety diagnostic that the device incorporates is global self-test, which performs an initial verification of the proper assignment of I/O pins and verifies that the power supply is present and healthy. To further ensure the accuracy of the test, the SD113E performs a series of analog self-check tests to provide the most reliable protection available.

The second safety diagnostic that the SD113E offers is local circuit diagnosis. This feature verifies the integrity of the local circuit breaker by monitoring the output of the breaker to ensure it is operating properly. If the breaker fails the test, the SD113E can notify the user or issue an alert in order to protect people and equipment.

Lastly, the SD113E provides global circuit diagnosis. This diagnostic tests the state of the entire circuit, by monitoring the state of the four breakers connected to it. If any breaker fails the test, the SD113E can issue an alert to the user or to a control system in order to protect people and equipment. The main purpose of these diagnostics is to ensure the proper operation of the connected circuit breakers and to protect against unforeseen hazards.

In conclusion, the SD113E safety device is designed to provide a high level of safety protection against electrical shock hazards in industrial applications. The device offers three safety diagnostics: global self-test, local circuit diagnosis, and global circuit diagnosis. By combining these three diagnostics, the SD113E offers comprehensive local and global protection, making it the perfect choice for high-volume and hazardous electrical environments.
