                This standard was drafted according to the rules given in GB\/T1.1\u20142009.
                This standard replaces JB\/T 8219\u20141999 “Electric Actuators for Industrial Process Measurement and Control Systems”. The main technical changes compared to JB\/T 8219\u20141999 are as follows:<\/p>

                • The title of the standard has been changed;<\/p><\/li>

                • The normative references have been updated (see Chapter 2);<\/p><\/li>

                • In the product classification, the original classification based on the relationship between actuator input and output is changed to classification by control method, dividing it into switch-type actuators and regulating-type actuators (see 4.1.2); a method based on the motor drive mode has been added (see 4.1.4); the “damping characteristics, gap, and dead zone” indicators in the 1999 version have been removed (see 4.2 of the 1999 version);<\/p><\/li>

                • The “proportional actuator input signal” from the original standard is modified to the preferred input signal for regulating-type actuators and switch-type actuators (see 4.2.5);<\/p><\/li>

                • Basic functions of intelligent actuators have been added (see Chapter 5);<\/p><\/li>

                • The accuracy grades have been changed from the original “Level 1, 2.5, 5” to “Level 0.5, 1.0, 1.5, 2.5” (see Table 1); the terms “proportional electric actuators” and “integral electric actuators” in the original Table 1 have been modified to “regulating-type actuators” and “switch-type actuators”;<\/p><\/li>

                • The requirements now include “maximum and minimum control torque and thrust repeatability errors”, “basic functions of intelligent actuators”, “RF electromagnetic field radiation immunity”, “electrical fast transient pulse group immunity”, “surge (impact) immunity”, “electrostatic discharge immunity”, and “power frequency magnetic field immunity” (see 6.1.13, 6.1.15, 6.2.6, 6.2.7, 6.2.8, 6.2.9, 6.2.10);<\/p><\/li>

                • Some test methods have been modified or added, such as temperature rise (see 7.13), environmental temperature effects (see 7.20), power supply voltage effects (see 7.22), etc.
                  This standard is proposed by the China Machinery Industry Federation and is under the jurisdiction of the National Technical Committee for Industrial Process Measurement and Control and Automation Standardization (SAC\/TC124).<\/p><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                                        • Passive contact, DC 24V, AC 220V

                                          4.2.6 Switching Frequency<\/strong>
                                          The actuator works under an intermittent reversible duty cycle. When the duty cycle is between 20% and 80%, the number of switches per hour is chosen from the following series: 100, 320, 630, 1200, 1800.
                                          Note 1: The duty cycle refers to the ratio of the actuator’s motor power-on time to the motor power-off cycle time, expressed as a percentage.
                                          Note 2: The duty cycle, switching frequency, and switching time per hour can be specified differently based on user requirements.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                                          5.1 Display Function<\/strong>
                                          Intelligent actuators can display operational parameters, running status information, signal queries, fault alarms, etc., through a human-machine interface, in Chinese (or other languages according to user requirements).<\/p>

                                          5.2 Parameter Setting Function<\/strong>
                                          Intelligent actuators can set working parameters such as stroke and torque through the human-machine interface. They can also calibrate 4mA-20mA current output signals.<\/p>

                                          5.3 On-site Configuration Function<\/strong>
                                          Intelligent actuators must have at least the following on-site configuration functions:<\/p>

                                          • On-site setting of the switch contact mode for outputting operational status<\/p><\/li>

                                          • On-site setting of control modes for both remote and local control<\/p><\/li><\/ul>

                                            5.4 Fault Self-Diagnosis and Alarm Function<\/strong>
                                            Intelligent actuators can self-diagnose abnormal conditions that occur during operation (e.g., motor overheating, power phase loss, valve jamming) and automatically display fault information locally and output alarms remotely.<\/p>

                                            5.5 Communication Function<\/strong>
                                            Intelligent actuators can be equipped with optional digital communication interfaces for fieldbus communication control. The fieldbus protocol used should be tested by a relevant authoritative testing agency to confirm whether it complies with the corresponding fieldbus standards.<\/p>

                                            5.6 Other Functions<\/strong>
                                            Intelligent actuators may also have the following functions:<\/p>

                                            • At least 4 switch contact outputs (with no less than 2 switch contacts that retain their status after power loss)<\/p><\/li>

                                            • Power phase sequence self-adaptation function<\/p><\/li>

                                            • Position sensors should preferably be non-contact absolute encoders that do not require battery support<\/p><\/li>

                                            • Torque sensors can continuously measure the actuator’s output torque (thrust)<\/p><\/li>

                                            • For high-precision control or cases requiring multi-stage speed control, actuators with stepless (frequency) speed control functions should be preferred<\/p><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
