This is the 24V variant of the 7-24V Modbus RTU 1, Channel Relay Module, RS485/TTL Anti-reverse, Connection in Relay Modules. Available at ₹446.04 (₹378.00 + GST) with free shipping across India.

PRODUCT DESCRIPTION

The LC 1-channel Modbus relay module employs a dependable 8-bit MCU and an RS485 level communication chip. It adheres to the standard MODBUS RTU format and RS485 communication protocol. This module is capable of detecting a single-way input signal and managing a single-way relay output, making it ideal for digital detection or power control applications.

Features:

1. On-board mature and stable 8bit MCU and MAX485 level conversion chip

2. Communication protocol: support standard Modbus RTU protocol

3. Communication interface: Support RS485 / TTL UART interface

4. Communication baud rate: 4800/9600/19200, default 9600bps, support power saving

5. Photocoupler input signal range: DC3.3-30V (This input cannot be used for relay control)

6. Output signal: relay switch signal, support manual, flash-off, flash-off mode, the delay base of flash-off / flash-off is 0.1S, the maximum settable flash-off / flash-off time is 0xFFFF * 0.1S = 65535 * 0.1 S = 6553.5S

7. Device address: range 1-255, default 255, support power-down save

8. Onboard one 5V, 10A / 250V AC 10A / 30V DC relay, which can continuously attract 100,000 times, with diode leakage protection, short response time

9. Onboard relay switch indicator

10. Supply voltage: DC7-24V, with input anti-reverse protection

QUICK OVERVIEW:

1VCC, GND: DC7-24V power input
GND: DC3.3-30V optocoupler signal input
A +, B-: RS485 communication interface, A +, B- are connected to A +, B-
Relay switch signal output
NC: normally closed end, the relay is short-circuited to COM before pull-in, and left floating after pull-in;
COM: public end;
NO: Normally open, the relay is suspended before the pull-in, and shorted to COM after the pull-in.
Relay indicator: lit when the relay is on
GND, RXD, TXD: TTL level UART communication interface, GND, RXD, TXD are respectively connected to GND, TXD, RXD of the external control terminal
