31G1-2117T is one of the Panel Indicators, Pilot Lights, designed to flag or alert the user to particular malfunction in the system. It usually takes on a form of LED indicator working with either AC or DC power circuit. It comes with various mounting accessories such as hoop connection, panel mounting, removable or snap-in terminal array.

The working principle of 31G1-2117T is based on the connection between two metal parts having different resistance values for electricity flow. It resembles a bulb, but it is actually constructed from LEDs which are much efficient as they consume lesser wattage and possess more endurance against external stress than a standard bulb. The LED is soldered to two copper lines - a positive line and a negative line. The lines are linked to either AC or DC circuit, furnishing the LED with the required current. A resistor is also linked in series with the LED so that it doesn’t receive too much current.

When a current of appropriate voltage is passed through the two lines, the LED emits light. The 31G1-2117T is characterized by two colors, a red one for when alarm is triggered, and a green one to signify that everything is in order. This works by controlling the current running through the LED. To turn off one of the colors, the current is bypassed from it, leaving the other to glow. To get the desired level of brightness, the lines have to be properly soldered so that the voltage stays between the required range.

The 31G1-2117T is best suitable for operating in the temperature range 20°C - 55°C, impacting the effective range of the device. It is prolifically used in various industrial and automotive monitoring applications, such as warning when a system has failed, overriding of the system, and in malfunction detection. It also finds its application in charging control and feeding operation of starters.

The use of a LED indicates that the device is clearly visible even in daytime or in brightly lit rooms. This is one of the useful aspects of such device, and also the fact that it consumes lesser energy compared to a conventional bulb.

The 31G1-2117T is one of the best choice for applications which requires complete visibility and great durability. It also offers secure and reliable connection with the use of its hoop, removable and snap-in terminals. Its versatility, durability, dependability and cost efficiency makes it an all-rounder in the field of Panel Indicators, Pilot Lights.
