DC 12V 24V 2Ch DB9 UART Relay Module RS232 Serial Port Switch Board for PC PLC Motor LED PTZ
Package inlcuded
:
1PCS
2 channels DC12V 24V RS232 PC UART Relay Module
Product Features
1.Working voltage: DC 12V/24V;
2.Working current: Standby 12MA, 1 relay conducts 40MA, 2 relays conducts 67MA,
3.Relay output isolation;
4.The communication interface supports RS232 DB9 serial port;
5.Communication baud rate: 9600;
6.Communication control: use the provided command control;
7.Relay channel: 2;
8.With relay status indicator and power indicator;
9.With jog function, you can use the command to operate the relay to open for a period of time and automatically close.
Product Features
1. 2-channels relay controler;
2. RS232 serial input control;
3.The on/off status of the relay can be read;
4..Support self-locking mode (reverse state of relay, if relay NO and COM are closed, send this command to disconnect NO from COM, and vice versa);
5.
Support momentary mode
(relay NO is closed with COM, and disconnected after 200MS);
7.Support interlock mode (corresponding relay is closed, other relays are disconnected);
8.Support control single relay on/off operation
9.Support simultaneous control of multiple relay on/off operations.
The main parameters
Wiring Diagram
Instructions For Use
Connect to the controller through a USB to RS232 module , connect the module to the PC, open the serial port debugging assistant, select the corresponding port, select the baud rate 9600, no parity, 8 data bits, 1 stop bit.
Example: To turn on all relays, send the command 55 56 00 00 00 03 06 AA, 0x5556 is the frame header, 0x000000 is the reserved byte, 0XFF is all relays, 0x06 is the command, which means multiple relays on/off operation, 0XAA As the terminator, the effect of sending the command is as shown below.
