Installation
optoNCDT 2300
5.6.2 Supply Voltage
Nominal value: 24 V DC (11 ... 30 V, max. 150 mA).
Switch on the power supply unit, once wiring is completed.
Connect the inputs “1“ and “2“ at the sensor with a 24 V voltage supply.

Supply
Use the supply voltage for measurement instruments only and not for
drive units or similar sources of pulse interference at the same time.
MICRO-EPSILON recommends using an optional available power supply
unit PS2020 for the sensor.

5.6.3 Laser on
The measuring laser on the sensor is activated via an optocoupler input. This is advantageous if the sensor has to be switched off for
maintenance or similar. Switching can be done with a transistor (for example open collector in an optocoupler) or a relay contact.

If pin Pin 3 is not connected with +U

and Pin 4 is not connected with ground, the laser is off. The wiring for laser on/off with the
supply voltage is already done in the PC2300-x/SUB-D and PC2300-0, 5/Y cables.

There is no external resistor for current limiting re-
quired. Connect Pin 1 with 3 and Pin 2 with 4 for
permanent „Laser on“.
Reaction Time for Laser-On: Correct measuring data
are sent by the sensor approximately 1 ms after the
laser was switched on.
