It provides 32 relay channels, with each relay featuring a 1NO + 1NC contact form and a contact rating of ≤10A 250VAC\/30VDC, making it suitable for controlling AC and DC loads within the specified limits.\u003c\/p\u003e\n\u003cp\u003eThe module operates from a wide 7–36V DC power supply and supports RS485 communication baud rates of 4800, 9600, 19200, 38400, 57600, 115200, 128000 and 256000 bps, with 9600, N, 8, 1 as the default communication format. Its RS485 address can be configured from 1–255, allowing multiple relay modules to be cascaded on the same RS485 bus.\u003c\/p\u003e\n\u003cp\u003eFor dependable operation in industrial environments, the module integrates power supply isolation, magnetic isolation, optocoupler isolation, a resettable fuse, TVS protection, reverse-polarity protection and freewheeling diode protection. It also supports flash-on and flash-off relay control through commands, while the STA, TXD and RXD LEDs provide convenient status and communication indication.\u003c\/p\u003e\n\u003cp\u003eThe rail-mounted ABS enclosure makes the 32-channel Modbus relay module easy to install and suitable for industrial automation, remote equipment switching, machine control and other applications requiring reliable RS485 relay control.\u003c\/p\u003e\n\u003ch2\u003eFeatures:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCascade several devices on the RS485 bus with configurable device addresses (1-255).\u003c\/li\u003e\n\u003cli\u003eFeatures flash-on, flash-off function, it is possible to turn on the relay for a long time and then close it automatically by the command.\u003c\/li\u003e\n\u003cli\u003eThe onboard voltage regulator chip allows a wide voltage power supply from 7 to 36V.\u003c\/li\u003e\n\u003cli\u003eOnboard unibody power supply separation delivers stable isolated voltage and does not require an additional power source for the isolated terminal.\u003c\/li\u003e\n\u003cli\u003eOnboard unibody magnetic isolation provides signal isolation, great reliability, robust anti-interference, and 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, providing over-current\/over-voltage proof, lightningproof, and anti-electrostatic.\u003c\/li\u003e\n\u003cli\u003eOnboard Optocoupler isolation protects the relay from interference from high-voltage circuits.\u003c\/li\u003e\n\u003cli\u003eThe driving ability is greater and more steady thanks to the onboard dedicated relay driver chip, which includes freewheeling diode protection.\u003c\/li\u003e\n\u003cli\u003eReverse-proof circuit prevents the circuit from being accidently destroyed by an incorrect connection.\u003c\/li\u003e\n\u003cli\u003eHigh-quality relay with contact rating of ≤10A at 250VAC\/30VDC.\u003c\/li\u003e\n\u003cli\u003eRail-mounted ABS enclosure is easy to install and safe to use.\u003c\/li\u003e\n\u003cli\u003eThree LEDs indicate the MCU state and signal transceiving status.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Waveshare","offers":[{"title":"Default Title","offer_id":54401030750432,"sku":"TIFKT0388","price":6999.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0559\/1970\/6265\/files\/Waveshare_32-Channel_Modbus_RTU_Relay_Module_with_RS485_Interface_Isolation_Protection.png?v=1787569632","url":"https:\/\/robocraze.com\/products\/waveshare-32-channel-modbus-rtu-relay-module","provider":"Robocraze","version":"1.0","type":"link"}
