Trumpai apie prekę

Prekė: Relinis modulis Waveshare, 32 kanalai, RS485 Modbus RTU, montavimas ant DIN bėgelio. Kategorija: Priedai.

• Gamintojas: WaveShare
• Modelis: Modbus RTU Relay 32CH Waveshare 25140

Advanced solution for industrial applications, controlled via RS485 bus using Modbus RTU protocol. The device has been designed for reliability in difficult conditions – it has full power isolation, magnetic signal isolation and protective circuits such as TVS diodes and resettable fuses. The whole is enclosed in a safe ABS plastic housing adapted for mounting on a DIN rail.

Technical specification

• Working voltage: 7V ~ 36V
• Communication interface: RS485 (Modbus RTU protocol)
• Transmission speed: 4800 to 256000 bps (default 9600)
• Number of channels: 32
• Contact form: 1NO 1NC (switchable)
• Relay load: ≤10A 250VAC / 30VDC
• Addressing: configurable from 1 to 255
• LED indicators: MCU status (STA) and transmission (TXD, RXD)

Properties and protection

• Integrated power insulation for stable voltage
• Magnetic signal isolation to eliminate interference
• Surge protection (TVS) and reverse polarity protection
• Possibility of cascade connection up to 255 devices on one bus
• Instant on/off function (Flash-on/off)
• High-quality relays with diodes protecting the control system

Assembly and Communication

The module is fully compatible with the RS485 industry standard, which allows for stable communication over long distances. Thanks to the DIN rail housing, installation in control cabinets is quick and orderly.

Connection diagram and application

Ideal for industrial automation, smart home systems, motor control, lighting and monitoring systems. Relays support both alternating (AC) and constant (DC) voltages.
