INTRODUCTION

The ET-16 (incandescent and LEDs) and ET-17 (neon) indicating lamps consist of a common receptacle, plug in type resistors and lamps, escutcheon, and color cap. They are available for mounting on switchboard panels up to and including ¼ inch thickness.

APPLICATION

These lamps can be used whenever a panel mounted signal or indicating lamp is desired.

The ET-16 is available for either one brilliance or dim bright operation when incandescent lamps are used. ET-16 lamps are also available with Light Emitting Diodes (LEDs). The incandescent type can be easily upgraded to the LED type. It only requires acquiring the appropriate color LED and lens cap and inserting into the lamp receptacle.

The ET-17 can be used when extra long life is a factor and brilliance is not. It also can be used when low current is desired.

FEATURES

1.The simple “push-twist” type plug has been adopted for both the bulb and the resistor. This was accomplished by incorporating a bayonet base on both components.

2.A common receptacle for both the ET-16 and ET-17 coupled with the plug-in resistor and bulb makes it easy to change on the panel without disassembling.

3.The resistor is in series with the bulb, and the ohmic value for the different circuit voltages is designed at 80% of the rated bulb voltage to give it longer life. Changing voltages is easily accomplished by changing the series resistor (see listed tables for the proper resistor).

4.A short circuit plug is available when a series resistor is not required or if an external resistor is to be used.

5.The ET-16 uses GE Catalog No. 1819 for the 24 DC lamp and GE Catalog Number 1835 for the balance of the ratings. For LED types, long life LEDs (100,000 hours) are specified. Additional features are as follows: reduced heat, resistance to shock and vibration, improved safety, lower current, cost savings, and no cold filament inrush current. The LED lamps come in red, green, and amber colors. White is not an option because a white light LED is not available. ET-17 uses GE Catalog Number B1A.

6.Terminals are readily available. They are designed for either AMP “FASTON” type connectors, solder, or screws.

7.Nine basic color caps designed for maximum visibility are available for ET-16 incandescent types. Five Translucent caps: red, green, yellow, white; and four transparent caps: amber, red, green, blue, and clear. For ET-16 LED types, only the transparent lens caps are recommended. This is because the transparent lens allows more LED light to pass through than the translucent lens cap used on incandescent lamps. The available colors are as follows: red, green, amber, yellow smoke, clear and blue.

ET-17: Because of the special properties of neon, only amber, transparent red, and clear lenses are suitable.

The color caps have a knurled OUTSIDE DIAMETER FOR EASY REMOVAL.

8.The ET-16 is also available for dim bright applications.

9.When special voltage or resistance is required other than those listed, a special lamp may be ordered with the proper design, or designated series resistor.

10.A two-inch insulating washer is supplied with each indicating light. It should be mounted on the inside of the panel as illustrated in Figs. 2, 3, and 4. The function of this washer is to provide additional insulation between the terminal and ground (panel) if a surge were to be induced on one of the potential leads.

If a bulb other than those listed above is required, the lamp will be furnished less the bulb. Listed tables give some of the specials made available.

ET-16 specifications

The GE ET-16 is a remarkable electric locomotive produced by General Electric Transportation (now part of Wabtec Corporation) that has gained widespread recognition in the rail industry. It is notably known for its powerful performance, advanced technologies, and versatility in freight transportation. Developed in the late 1970s, the ET-16 was designed to accommodate the increasing demands of rail freight and to compete with other manufacturers' offerings.

One of the standout features of the GE ET-16 is its robust traction system. It employs a powerful GE 752 traction motor, providing significant tractive effort and enabling it to haul heavy freight loads effectively. With a power output of around 3,200 horsepower, the locomotives can efficiently manage various elevations and gradients, making them suitable for a variety of terrains.

The GE ET-16 is equipped with an innovative, modular design that allows for easier maintenance and upgrades. This flexibility enhances the lifespan of the locomotive, making it a favored choice for many freight rail operators. The design also allows for the integration of newer technologies, ensuring that the locomotive remains competitive with modern advancements in locomotive engineering.

In terms of technologies, the ET-16 features sophisticated digital controls enhancing its operational efficiency. This includes advanced microprocessor-based systems that optimize performance based on real-time data, improving fuel efficiency and reducing operational costs. Additionally, the locomotive’s braking system utilizes dynamic braking technology, allowing for smoother stopping and less wear on mechanical parts.

Another notable characteristic of the GE ET-16 is its versatile configuration options. Operators can customize the locomotive to suit specific operational requirements, such as different gearing ratios or wheel configurations. This adaptability extends its usability across various sectors, including intermodal, bulk freight, and heavy goods transportation.

Moreover, the ET-16 is designed for enhanced safety features, including an improved visibility cab that provides the engineer with a clear panoramic view of the tracks. Emergency braking systems and advanced signaling technology are also part of its safety package, allowing for a reliable operating environment.

In summary, the GE ET-16 is a powerful and versatile electric locomotive that incorporates advanced technologies and features designed for efficient freight transportation. Its modular design, sophisticated control systems, and adaptability make it a standout option for rail operators aiming to meet the evolving demands of the transportation industry. The legacy of the GE ET-16 continues to influence locomotive design and engineering, representing a significant step forward in electric locomotive technology.
