It supports three distinct switching modes per channel: self-locking (standard on\/off), interlock (opening one channel automatically closes the others), and inching (channel opens then auto-closes after 0.5–3600 seconds).\u003c\/p\u003e\u003cp\u003eLike the 4CHR3, it connects via IEEE 802.11 b\/g\/n at 2.4 GHz and is managed through the eWeLink app on Android and iOS. Voice control is available through Amazon Alexa, Google Assistant, and Samsung SmartThings. Timer scheduling (single, repeat, and countdown) operates independently of network availability. Device sharing allows other eWeLink accounts to control the switch.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFour independent output channels, each rated at 10A\/2200W\u003c\/li\u003e\n\u003cli\u003eTotal rated load: 40A\/8800W\u003c\/li\u003e\n\u003cli\u003eSelf-locking mode: independent on\/off for all 4 channels\u003c\/li\u003e\n\u003cli\u003eInterlock mode: opening one channel closes the other three simultaneously\u003c\/li\u003e\n\u003cli\u003eInching mode: channel opens then auto-closes after 0.5–3600s\u003c\/li\u003e\n\u003cli\u003eRF support: any 433MHz control\u003c\/li\u003e\n\u003cli\u003eRemote on\/off via eWeLink app (iOS and Android)\u003c\/li\u003e\n\u003cli\u003eTimer scheduling: single, repeat, and countdown\u003c\/li\u003e\n\u003cli\u003eDevice sharing with other eWeLink accounts\u003c\/li\u003e\n\u003cli\u003eVoice control: Amazon Alexa, Google Assistant, Samsung SmartThings\u003c\/li\u003e\n\u003cli\u003eWi-Fi IEEE 802.11 b\/g\/n 2.4 GHz (2400–2483.5 MHz)\u003c\/li\u003e\n\u003cli\u003eSecurity: WPA\/WPA2; Encryption: WEB\/TKIP\/AES\u003c\/li\u003e\n\u003cli\u003eEnclosure: PC V0, IP20 protection\u003c\/li\u003e\n\u003cli\u003eCertifications: CE\/FCC\/RoHS\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInterlock mode is purpose-built for motor or actuator control where only one direction can be active at a time\u003c\/li\u003e\n\u003cli\u003eInching mode enables automatic gate or door actuators that must close after a fixed period\u003c\/li\u003e\n\u003cli\u003eRF 433MHz support allows control from a physical remote without relying on the internet or smartphone\u003c\/li\u003e\n\u003cli\u003e40A\/8800W total load capacity accommodates heavier combined loads across all four channels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Colour:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Material:\u003c\/strong\u003e PC V0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Rating:\u003c\/strong\u003e IP20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Systems:\u003c\/strong\u003e Android and iOS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoice Assistant Compatibility:\u003c\/strong\u003e Amazon Alexa, Google Assistant, Samsung SmartThings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWireless Frequency:\u003c\/strong\u003e Wi-Fi 2.4 GHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWireless Standard:\u003c\/strong\u003e IEEE 802.11 b\/g\/n 2.4 GHz (2400–2483.5 MHz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecurity Mode:\u003c\/strong\u003e WPA\/WPA2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEncryption Mode:\u003c\/strong\u003e WEB\/TKIP\/AES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Temperature Range:\u003c\/strong\u003e -10°C to 40°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRF Support:\u003c\/strong\u003e Yes, any 433MHz control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput:\u003c\/strong\u003e AC 100–240V 50\/60Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e AC 100–240V 50\/60Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax.
