A compact IP65 screw mounted motor brake relay starter combination, designed for DOL 3 phase motors.
SX 9033N is suitable for motors rated from 500W to 7.5kW, braking current (IB) is adjustable via a potentiometer scaled 10-100% (2.5A to 25A). Indication is via three LEDS’ which indicate power connected (green), fault indication (red) and DC current injection(yellow).
The BA9034N brake module incorporates standstill monitoring and an internal contactor connecting the DC output of the brake relay to the motor. The inter-lock contact X5 –X6 is utilised to avoid motor restart while injecting braking current and a built in safety brake override timer will stop the braking cycle if standstill is not detected within the safety time.Braking is normally initiated by a close - open - close Volt free contact sequence at terminals X3 – X4,
