2.7.10 LED display indicator module
2.7.10.1 Description
The LED display indicator module can be connected to the coil terminals of size S00 and S0
contactors; it indicates the energized state of the contactors via yellow LEDs. In practice the
LED display indicator module is primarily used for 3RT2 power contactors in size S0.

The LED display module can be used for voltages of 24 to 240 V AC/DC. The LEDs are
switched on a bidirectional basis in order to ensure they are protected against polarity
reversal. With AC control both LEDs light up and with DC control just one LED lights up,
depending on the polarity.
2.7.10.2 Mounting
The LED display indicator module is snapped into the location hole on the front of the
contactor, in place of the labeling plate.
