entrance gates, etc.
• Operates electrical motors, which are controlled in 2 directions and
have a built-in limit switch.
• JA3-02B/DC controls electric drives with supply voltages up to
24 V DC, where the direction of rotation of the driver is controlled by
changing the voltage polarity of the motor.
• The unit is equipped with thermal and overcurrent overload protection outputs.
• Status of units is indicated by green LED RUN on the front panel:
– with the supply voltage connected (through BUS) and the unit is not
controlled by BUS, LED RUN shines.
