POWER IN - terminal #1 & #2
Input power to terminal #1
&
#2 from power supply. AM04-1allows 18VAC or 20-24VDC input.
A
DC
linear power supply will make system more stable.
The power input without polarity requiring, but a shield cable is necessary.We connect the power cable
according to the figure above just for the background LED which is connected at POWER OUT.
POWER O U T - terminal #1 & #2
Used for output power to another AM04-1 board or background LED. For multiple antenna install,
power supply should provide enough current for all boards which is series connection. For example,
two
AM04-1 board
series
connection
together,
power
supply should
provide
at
least
2x600mA=1200mA current.
A N T I N
Used for connecting RX antenna coil or matching board to this connector.
ANT OUT
Used for connecting TX antenna coil to this connector.
LED
Used for connecting an alarm lamp or remote 24V buzzer. Maximum 24V 60mA
