Operation Mode of HW521 Adjustable Timing and External Trigger Power Relay Module

  • P1 : Trigger signal, the relay is on “OP” time, and then disconnect; Within the “OP” time, proceed as follows:
  • P1.1 : the signal is triggered again, invalid
  • P1.2 : the signal is triggered again, re-clocking
  • P1.3 : Signal has triggered again, the relay is disconnected, stop the clock;
  • P-2 : Trigger signal, after the “CL” time is off, the “OP” time is on. When the timing is completed, the replay will be disconnected;
  • P3.1 : Trigger signal, after the “OP” time is on, the “CL” time is off, then cycle the above actions. If trigger signal within the loop, the relay will be disconnected and stop the clock. The number of cycles ( “LOP “) can be set.
  • P3.2 : No need to trigger the signal after powering up, the “OP” time is on, the “CL” time is off, then cycle the above actions; The number of cycles ( “LOP “) can be set.
  • P-4:  Signal holding function. If the signal is triggered, timing is cleared, the relay remains on; when the signal disappears, the relay will be off when the “OP” time is over; if another signal is triggered during timing, timing will be cleared.

How to choose the time interval:

  • parameter Introduction: OP power over time, turn off time CL, LOP cycle times (1-999 times, “—” is unlimited cycle)
  • 1. In the selection of parameter set interface mode, and press the STOP button to select the time.
  • (1)xxx. if the decimal point is in some place, the time interval is s-1 999 s
  • (2)xx. x is the decimal place is ten, the time interval is 0.1 s 99.9 s-
  • (3)x. x. x is the decimal point are all on, the time interval is 1 min-999 min

How to set the parameter:

  • First, make sure relay operation mode
  • According to the operating relay mode, the main interface (power module will flash current operating mode; standard mode P1.1, then come into the main interface); long press SET key two seconds and then choose and enter selection interface mode; by pressing UP, DOWN key to choose the mode setting  (P1.1 ~ P4)
  • After selecting the mode, press short SET to set the corresponding parameter, then the parameter you want to set will flash (OP power in time; CL power off time; LOP cycle times, “—” is unlimited cycle ); by UP, DOWN to set the parameter value, support long press (increase or decrease quickly) and press slightly (increase or decrease of 1 unit); after setting the parameter value by short press the STOP key to choosing decimal place; choose the time interval (corresponding time interval is 0.1 s-999 min); Short press SET to set the current mode next parameter, the process is the same as above
  • After the setting mode parameter, press and hold the SET button then hold the current configuration mode will flash, then go back to the main interface; define success parameter main interface: when the relay does not work, it will show “000” (no decimal point); the operating state relay, the screen has a decimal point

Features of HW-521 Adjustable Timing Cycle Power Relay Module

  • Optocoupler Isolation: improve the anti-interference ability, after the parameter setting, it will be in memory forever.
  • Wide voltage power supply (6 ~ 30V), supports micro USB 5.0V power supply, easy to use.
  • The interface is clear, simple, powerful and easy to understand, can meet almost all your needs.
  • With emergency stop function (“STOP” button) and reverse polarity protection which can avoid burning by reverse connection.
  • Adding sleeping mode, when the mode is enabled, if there is no operation within 5 minutes, the display will be turned off automatically, press any button will wake it up;
  • You can set different parameters of OP, CL, LOP, which are independent of each other and are stored separately;
  • All the parameter settings will be stored automatically when power is off.
