JY-30 with counting time control timing board power control board design can set the time




JY-21 4-way coin-operated countdown time control board timing board 4-way relay control power supply
Input voltage: DC 12V
Output voltage: consistent with the voltage input by interface 13
Main functions: coin input → press the start button of the device → time countdown, the device works → the time ends → the device stops working
Can control 1-4 devices
Load: The sum of the equipment at work does not exceed 15A
Price and time can be set individually for each route
You can check the balance and show the remaining time
Pulse input such as coin acceptor and banknote device can be connected
Accessible counters to query income

2 section price and time:
First section price and time for Machine start working- First use
Second section price and time when machine is working- CONTINUOUS USE
Example setting: First use- 2 dollar for 10 mins, CONTINUOUS USE- 1 dollar for 6 mins.
Insert 2 dollars--> machine start working for 10 mins-> Insert 1 dollar in 10 mins--> add 6 mins.
User has to insert 2 dollars when machine is standby.
Detail Function
| Input Voltage | DC+12V |
| Standby | Display shows:00:00, reply: Normal Open (NO) |
| Accumulated time | Yes, add time if receive signals again when time is running |
| Max current load | 15A |
| How it works | |
| Mode 1 | Time runs down after receive signals-> Display shows remaining time and supply power to device-> it cuts off power after time runs out |
| Pause (connect a button) | Push button pause: it cuts off power when pause, display shows remaining time. Re-supply power after push button pause again |
