MCU Relay Module, Intermittent Switching, N76E003

Description

Control:

• Based on MCU N76E003 controlled relay board, relay active on and off intermittently
• Can set 0~999 seconds (16-17 minutes) after to turn on relay. (also can program to 999 minutes or maybe hours in more complex level)
• Also can set 0~999 after to turn off relay or hold on relay.
• One extra input signal, can use to control board by programming.
  • fully isolated by optical coupler
  • In current demo code, will work as “emergency button”, when send signal will hold current loop to stop.
  • Can also connect to board ground, to eliminate the isolation
• MCU flashed with bootloader, you can upload code by USB-TTL debugger, no need special programmer.

Power Supply:

• Wide range input voltage 5-37V by regulator LM317
• Protective diode to prevent wrong direction power connection.
• Support USB power.

Other Features:

• On board songle SPDT relay 10A /28VDC or 240VAC.
• On board segment display to show timing.
• One relay signal led indicator
• Two config buttons, only two used.
