In the paper production process, electrical appliances are usually controlled by an inverter, which can only measure the total current, not the current consumption of individual motors. By connecting a monitoring relay upstream of each motor and measuring the power consumption similar to a higher level process control transmission, it is possible to make very precise measurements at low frequencies and monitor individual motors precisely at process level.<\/li><li>In addition to current measurements, the monitoring relays also record the operation of the transmission belt drive motors and transmit them to higher-level control units. Compared to inverters only, the use of monitoring relays makes foundation control more resistant to interference and ensures that data processing can be carried out in the central control unit while the equipment is measured in a decentralized and flexible manner.<\/li><li>In addition, the monitoring relay can also control the inverter, which is usually controlled by signals from the PLC. If the monitoring relay is connected between the PLC and the inverter, the control signals from the PLC can be monitored, thus improving system safety.<\/li><\/ol>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\" style=\"grid-template-columns:36% auto\"><figure class=\"wp-block-media-text__media\"><img decoding=\"async\" width=\"281\" height=\"377\" src=\"https:\/\/hongtronics.com\/wp-content\/uploads\/2022\/08\/\u7e7c\u96fb\u5668.png\" alt=\"\" class=\"wp-image-22806 size-full\" srcset=\"https:\/\/hongtronics.com\/wp-content\/uploads\/2022\/08\/\u7e7c\u96fb\u5668.png 281w, https:\/\/hongtronics.com\/wp-content\/uploads\/2022\/08\/\u7e7c\u96fb\u5668-224x300.png 224w\" sizes=\"(max-width: 281px) 100vw, 281px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<ul class=\"has-background has-medium-font-size wp-block-list\" style=\"background-color:#eafbd7\"><li>G2FW400VL20<\/li><li>GAMMA Series<\/li><li>Measurement Voltage<\/li><li>Power Failure Monitoring<\/li><li>Under- and over-frequency monitoring<\/li><\/ul>\n<\/div><\/div>\n\n\n\n<div style=\"height:26px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-16018d1d wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button has-custom-font-size has-medium-font-size\"><a class=\"wp-block-button__link has-background\" style=\"background-color:#85a932\">02 Monitoring Relay Application in Machine Tools<\/a><\/div>\n<\/div>\n\n\n\n<ol class=\"has-medium-font-size wp-block-list\"><li>For some production lines where the temperature of the machine tool is more stringent, it is necessary to turn on the ventilation equipment at the same time when the machine starts up to ensure stable production. The monitoring relay HK-E3IF500 current measurement module can measure the current consumption of the machine and turn on the external ventilation when the current is greater than 500mA, and the monitoring relay can conduct a maximum current of 16A, thus making it easy to control the whole system with just one switch under a high continuous current load without the need for additional current transformers. This makes it possible to control the entire system easily with a single switch without the need for additional current transformers even under high continuous current loads.<\/li><li>On lathes and other machines, the chip conveyor usually collects and transports the waste from the lathe. In case of overload or blockage, the chip conveyor system has to be shut down automatically, and the monitoring relay HK-G2IM5AL20 can detect the load status of the conveyor system by monitoring the current consumed by the drive motor and shut it down quickly and reliably in case of overload or blockage, thus avoiding the delay of manual operation and extending the service life of the chip conveyor. This eliminates delays in manual operation and extends the life of the chip conveyor.<\/li><\/ol>\n\n\n\n<div class=\"wp-block-media-text has-media-on-the-right is-stacked-on-mobile is-vertically-aligned-center\" style=\"grid-template-columns:auto 27%\"><figure class=\"wp-block-media-text__media\"><img decoding=\"async\" width=\"313\" height=\"450\" src=\"https:\/\/hongtronics.com\/wp-content\/uploads\/2022\/08\/\u7e7c\u96fb\u56682.png\" alt=\"\" class=\"wp-image-22807 size-full\" srcset=\"https:\/\/hongtronics.com\/wp-content\/uploads\/2022\/08\/\u7e7c\u96fb\u56682.png 313w, https:\/\/hongtronics.com\/wp-content\/uploads\/2022\/08\/\u7e7c\u96fb\u56682-300x431.png 300w, https:\/\/hongtronics.com\/wp-content\/uploads\/2022\/08\/\u7e7c\u96fb\u56682-209x300.png 209w\" sizes=\"(max-width: 313px) 100vw, 313px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<ul class=\"has-background has-medium-font-size wp-block-list\" style=\"background-color:#eafbd7\"><li><strong>HK-E3IF500<\/strong><\/li><li>ENYA Series<\/li><li>Undercurrent monitoring<\/li><li>2 switching contacts<\/li><li>Measuring range:16A AC <\/li><\/ul>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-16018d1d wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button has-custom-font-size has-medium-font-size\"><a class=\"wp-block-button__link has-background\" style=\"background-color:#85a932\">03 Monitoring Relay Application in Pulverizer<\/a><\/div>\n<\/div>\n\n\n\n<ol class=\"has-medium-font-size wp-block-list\"><li>Similar to the above applications, monitoring relays can also be used in other scenarios, e.g.: when pulverizing different materials in a shredder, if the roller chopper is clogged, an abnormal current will occur.<\/li><li>A monitoring relay can be connected to the PLC and the present values of the different materials can be stored in the PLC.
