Technical Parameters:

Ethernet remote control The RS485 module sends the relevant commands to the module by receiving computer software to achieve the purpose of the control relay not being disconnected.

●Each of the four relays has three free interfaces (normally-open NO, normally-closed NC, and common-end COM). Each relay has an indicator next to it. When the relay is closed, the indicator is on, otherwise it is off.

●The address of the module is obtained by an 8-digit dial switch (1 to 4 for floors and 5 to 8 for classrooms). See the dial switch setting method for details.

●The module adopts the method of AC 24V power supply, which has the advantages of long transmission line and low power attenuation;

●The module adopts the standard 485 communication mode, which has the ability to suppress common-mode interference, low cost, and communication distance.
 
Timing control area:
“Timed Control On” button: When the system time reaches the set time, all the relays in the bus pull in.
“Timed Control Off” button: When the system time reaches the set time, all the relays in the bus are disconnected.
