COM : Connect to external GND terminal.
OUT 1,2,3,4 : This signal output circuit is open-collector output of a transistor.
Use external power source(up to DC 30V) for driving relay.
In case to need the signal of TTL, connect to pull-up resistance as the follows.
OPTION 3
Relay Output Function
(Max. DC30V, 100mA - ZERO, LOW, OK, OVER)
1) Charge Board: This board can charge Ni-Cd DC 7.2V, 2000mAh battery
2) Ni-Cd Battery: DC 7.2V, 2000mAh battery pack
3) Install
Connect output port of Ni-Cd battery pack to CN3 of charge board.
Connect output port of adapter to CN1 of charge board after confirming
polarity of adapter.
Connect CN2 of charge board to CN1 of CI-2400BS main board.
4) Method
If adapter code is connected to AC power to charge the battery power lamp is
ON.
When charging battery, charging lamp(RED lamp) is ON.
When the charging is completed, charging lamp(GREEN lamp) is ON.
It takes approximately 3-4 hours to charge in full.
