{"product_id":"modbus-rtu-16-channel-relay-module","title":"Modbus RTU 16-Channel Relay Module","description":"\u003cp\u003eWith 16 individual relay channels, this module provides an extensive capacity to manage many devices or equipment simultaneously. Whether you're controlling pumps, motors, heaters, or other machinery, the relay module offers a comprehensive solution for orchestrating various processes with precision. Equipped with built-in protection circuits including power supply isolation, ADI magnetical isolation, resettable fuse, and TVS diode, this module safeguards your equipment and data against power surges, electromagnetic interference, and short-circuits.\u003c\/p\u003e\n\u003cp\u003eIt supports the widely-used Modbus RTU protocol, allowing you to configure the device address within the range of 1 to 255. Furthermore, this module can be seamlessly integrated into existing setups, as multiple devices can be cascaded on an RS485 bus. This cascading capability simplifies complex installations and optimises communication across your network of devices.\u003c\/p\u003e\n\u003cp\u003eThrough the configurable device address and cascading functionality, you have the flexibility to create intricate automation systems tailored to your exact needs. Its extensive relay capacity, advanced protection features, Modbus RTU compatibility, configurable device address, and cascading capability make it an invaluable asset in managing complex processes while ensuring equipment longevity and data integrity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote: It is recommended to purchase the \u003ca href=\"\/ru\/products\/ft232rnl-usb-to-rs232-485-422-ttl-interface-converter\"\u003eUSB TO RS232\/485\/TTL\u003c\/a\u003e or \u003ca href=\"\/ru\/products\/usb-to-rs485-422-industrial-grade-isolated-converter\"\u003eUSB TO RS485\u003c\/a\u003e at the same time for easy testing.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eConfigurable device address (1~255), multi-devices can be cascaded on RS485 bus\u003c\/li\u003e\n\u003cli\u003eFeatures flash-on, and flash-off function, by passing argument to the command, it is possible to turn on the relay for a while and then close it automatically\u003c\/li\u003e\n\u003cli\u003eOnboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal\u003c\/li\u003e\n\u003cli\u003eOnboard unibody ADI magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption\u003c\/li\u003e\n\u003cli\u003eOnboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, provides over-current\/over-voltage proof, lightning proof \u0026amp;
