This photo shows a completely wired RPLG 2 wired for NPN sensors. The LEDs above the lower terminal are illuminated, indicating that each input receives a signal from a sensors of a GRZ gripper. The illuminated LED next to the lower terminal indicates that the RPLGs output is HIGH. The dark LED next to it illuminates when non of the RPLG inputs are HIGH.

How to wire a RPLG for NPN Sensors

RPLG_WireEvery RPLG features blade style terminals. Do not strip the isolation, just lift up the orange terminals, using a small screw driver and insert the wire. Then press hard on the orange terminal, you will feel how the knife cuts into the isolation of the wire. TIP: Remove the board from the box, strip the wires 3 inches (75mm)  and then insert them into the box. All wires will rest underneath the board.

Commonly used Color Code:

+24 V = Brown

       (-) = Blue

Signal = Black

RPLG_NPN2The terminals on the bottom connect from right to left: E1 = Input 1 black (signal) wire from sensor1,  (+) brown wire from Sensor 1  , E2= Input 2 black (signal)  wire from sensor 2, (+) brown wire from sensor 2


The terminal on the top, connects the (-) blue wire from the sensors

The terminal on the right connects the RPLG to the robot or PLC controller. From top to bottom: (-) the blue wire is the negative or common from the robot or PLC (+) brown wire is the positive feed for the box. (M) the black wire is the RPLG output (all sensors are ON) Terminal (<1) is not being used but this terminal is HIGH when ALL sensors (inputs) are low. 


Unused inputs need to be jumped in order to make the RPLG functional. Connect the free (-) terminal at the top with the free (E) terminal

You can run several RPLGs in series. Use the output (M) from one box and connect it with any Input (E) of the next RPLG
