Voltmeter Pilot Lights

Voltmeter pilot lights are panel indicators with an LED display in a pilot light-sized housing that shows numerically the voltage between the two terminals it is connected to. They are used in distribution and control panels to monitor the voltage of each phase separately and to notice a phase loss or undervoltage without opening the door. Gwest, Isıso and Konsan models that fit a 22 mm panel hole are offered in five different display colors; the measuring range is stated as 24-450 V AC for Isıso and Konsan products and 24-550 V for Gwest products. Choose the model so that the voltage to be measured stays within the measuring range, according to whether the voltage is AC or DC, the mounting diameter, and the display color that will distinguish the phases. These ranges cover both 230 V phase-neutral and 400 V phase-phase voltages. A voltmeter pilot light only displays the voltage; it does not replace a voltage protection relay, which opens the circuit through its output contact when the voltage goes out of limits.

How to choose Voltmeter Pilot Lights

Voltmeter pilot lights are panel indicators with an LED display in a pilot light-sized housing that shows numerically the voltage between the two terminals it is connected to. They are used in distribution and control panels to monitor the voltage of each phase separately and to notice a phase loss or undervoltage without opening the door.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
