MODBUS RTU 7-24V 2 CHANNEL RELAY MODULE RS485/TTL

2 channel Modbus relay module equipped with mature and stable 8-bit MCU and RS485 level communication chip,adopt standard MODBUS RTU format RS485 communication protocol, It can realize 1-way input signal detection and 2-way relay output, can be used for digital detection or power control occasions.

• • Supply voltage: DC7-24V, with input anti-reverse protection
  • Onboard one 5V, 10A / 250V AC 10A / 30V DC relay, which can continuously attract 100,000 times, with diode leakage protection, short response time
  • Photocouplers input signal range: DC3.3-30V (This input cannot be used for relay control)
  • On-board mature and stable 8 bit MCU and MAX485 level conversion chip
  • Communication protocol: support standard Modbus RTU protocol
  • Communication interface: Support RS485 / TTL UART interface
  • Communication baud rate: 4800/9600/19200, default 9600bps, support power saving
  • 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
  • Device address: range 1-255, default 255, support power-down save
  • Onboard relay switch indicator
