Industrial counting meter - Selec XC410

In Industry, Counting is very important parameter in production line. If we don't rely on technology than we need extra workforce for counting, Extra workforce means extra investment. Industries always try to reduce the work force & time consumption in production. That's why a counting meter is very useful device which reduces both time & workforce in production.

We can use counting meter of any company but basic wiring remains the same. In this post, we are going to discuss the SELEC make counting meter XC410.

COUNTING METER SELEC XC410

This small size counting meter comes in panel cutout of 29mm×71mm. Its display is 6digits, 0.3" height, Red 7 seg LED.

TERMINAL CONNECTIONS SELEC-XC410

• It has total 12 terminals. Terminals 10&12 are neutral & phase respectively, potential difference should be 230VAC (+-10%).
• Terminals 1&4 is 12 Volt DC positive & negative respectively. These terminals are used for proximity sensors.  Terminal 2 is PNP CNT, output lead of PNP sensor is connected to this point; Similarly ; terminal 3 is NPN CNT, output lead of NPN sensor is connected to this point.
• Resetting the XC410
  Terminals 5&6 used to enable front reset. If we don't short these two terminals than front reset button doesn't work. For remote reset there are terminals 4 & 5, Just short terminals 4 & 5.
• Input 7 & 8 are used to very the input speed. If input signal changes faster than we do not need to shot these two terminals but if input signal is slow than we have to short these two terminals.

Input connections

1. NPN/PNP  proximity Sensor

NPN/PNP sensors are three wired. 2 wires are power wires positive & negative while 3rd wire is signal wire. In PNP sensor, 3rd wire produces positive signal & on the other hand in NPN sensor, 3rd wire produces negative signal.

Power wires should be connected to 1(+12Volts) & 4(Negative) terminals while 3rd signal wire must be connected to 2nd terminal in PNP case & 3rd terminal in NPN case

NOTE: 

Sensor wire colors (Red=positive, Black=negative, Green= output & Brown=positive, Blue=negative, Black= output)

Sensor voltage should be 12 volt DC.

2. Potential free Contact

We can also use potential free contacts. The counting works only by shorting 3&4 terminals. 

SUMMARY

• SelecXC410 is a compact panel mount counting meter.
• It operates on 230VAC (+-10% ) supply.
• It has 6 digit LED display.
• Its takes inputs from 12VDC proximity sensors & potential free contacts.
• Both front & remote reset buttons are provided.
• It provides the option to select whether input signal is fast or slow.
• We can fit this on any machine panel. This meter provides all the options. It all depend upon us which input signal we want to use & how we set the logic for the counting.
