Typical applications:
1 AT command mode , in this mode can be through the serial HyperTerminal (serial assistant) enter a simple AT command control relay. AT command mode time up to 9999 seconds
2 MODBUS command mode, you can control a variety of ways: Serial Hyper Terminal Control (need to manually add the CRC), Modbus Poll software control (software automatically add the CRC), PLC or MCU process control
It can control 1-16 channels 5V/6V/9V/12V/24V Relay Module
With RS485 interface and RS232 (TTL) interface(It is recommended to remove the SP485 chip)
Version identification:
A version for esy insertion into existing relay boards
B version for easy embedding of custom PCB
