How to use BUSY signals
(Connection of UV irradiation indicators)
UJ20 has a 5 V DC (250 mA) external power supply.
Use this power supply and BUSY1 to BUSY4 in combination, and UV
irradiation indicators can be directly connected without any external
devices.
If the head cable length exceeds 2 m, use the BUSY signals to install
UV irradiation indicators in an easily viewable location for safety
purposes.
The external power supply is 5 V DC, and the maximum allowable load
current is 250 mA in total. The maximum allowable load current for
each BUSY signal is 100 mA.
