Description:
1. Relay output with LED indicator, easy to check the working status of the relay and whether it is running normally
2. UART protocol communication, baud rate 9600kbps, with 8 data bits and one stop bit, no parity
3. Each data frame contains eight bytes, which is safe, reliable and anti-interference
4. Each relay has normally open and normally closed contact, can be selected by jumper relay and TTL or ground
5. Relay modules are widely used in all MCU control, industrial sectors, PLC control, smart home control
Specifications:
Item Type: Relay Module
Power Input: DC 5V / 7-12V (Recommended 7.5V 9V)
PC Serial Port RS232 Control Relay
Power Indicator: LED Light.
Package list::
