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
Package Includes:
1 x 7-24V Modbus RTU 1 Channel Relay Module RS485
