, PLC controller is also called programmable logic controller, is a kind of microprocessor digital electronic equipment, used for automation control of digital logic controller, can control instructions at any time loading memory storage and execution, widely used in industrial control field.
Programmable logic controller (PLC)
for UL 61010-2-201 standard certification involves a series of steps to ensure compliance with measurement, control and laboratory electrical equipment safety requirements.
The following are the general steps for
UL 61010-2-201 certification:
the standard interpretation:
l Detailed understanding ofUL 61010-2-201 standard requirements, including electrical safety, mechanical safety, fire safety, environmental adaptability and other specific provisions.
l determine the PLC in the standardscope and special requirements.
Product Design and Evaluation: l According to the standard requirements, the
of PLC design evaluation, to ensure that its structure, materials and functions are in line with the standard.
to identify and resolve any potential security risks or non-conformations.
Test preparation for
:
l Prepare test samples, test equipment and test environment. lensure that test equipment and environments meet standard requirements for accuracy and reliability.
to do the test:
l According to UL 61010-2-201 standard requirements, the PLC electrical performance testing, mechanical performance testing, fire performance testing and environmental adaptability testing.Tests may include, but are not limited to,withstand voltage test, ground resistance test, insulation resistance test, temperature cycle test, humidity test, vibration test, etc.
Test Report and Review: Based on the test results, the
prepares a detailed test report containing test data, conclusions and recommendations.
