Question 1

Hi i buy one of this encoder, but, the colors of the wires are red, black, white and green. some idea about the connections?

Accepted Answer

Green is phase A and white is phase B you will need the red connected to positive voltage 5-24V and black to ground.Both phases will need to go to positive through a 2k pull up resistor. If you use arduino in my case Arduino Micro this is a sample code :
#define outputA 5
 #define outputB 6
void setup() {
   pinMode (outputA,INPUT);
   pinMode (outputB,INPUT);

}

void loop() {
  aLastState = digitalRead(outputA);  
  aState = digitalRead(outputA); // Reads the "current" state of the outputA
   // If the previous and the current state of the outputA are different, that means a Pulse has occured
   if (aState != aLastState){     
     // If the outputB state is different to the outputA state, that means the encoder is rotating clockwise
     if (digitalRead(outputB) != aState)  
       counter ++;
     else 
       counter --;
     
     Serial.print("Position: ");
     Serial.pr

Question 2

Does anyone have a datasheet for this? I need to know the arrangement of the screw holes.

Accepted Answer

Draw an equilateral triangle with 24mm long sides. The points are the hole centers.

Question 3

is there a wire diagram for connection of the encoder to the ab 1400 plc?

Accepted Answer

The encoder has the following wire connections Red>+24VDC Black>Ground Green and White Phase A and B.  You'll need to wire to specific inputs though. For example, if you use the first high-speed counter, you'll wire A and B channels to inputs 0 and 1 (A/ and B/ won't be used) with the signal low encoder wire going to COM0. Then you'll need to configure the HSC function file for a two-channel high-speed counter. The ML1400 Referenece Manual (1766-rm001) has all the details about using the high-speed counter. The user manual (1766-um001) has some additional (generic) information about wiring.

Question 4
