Operator Interfaces, Switches & Relays


Three-in-one status light

September 2005 Operator Interfaces, Switches & Relays

Banner Engineering is offering its EZ-Light smart indicator lights. These water- and oil-tight sealed units have colour lights - either continuous or flashing - that indicate the status of a machine or process. Developed to replace cumbersome post and stack lights with a single, compact unit that is sealed and IP67 rated, it features a rugged, solid-state design with no bulbs to burn out or replace.

EZ-Light is currently available in three configurations to perform in a variety of applications:

* 3-colour general purpose (red/yellow/green or custom colours).

* Multicolour 7-function featuring enhanced indication capabilities and flashing rates.

* A style that acts as a large remote indicator for EZ-Screen safety light curtain status.

Industry-standard housing styles include an in-line 18 mm barrel, right-angle 18 mm T-style and right-angle 30 mm T-style that are compatible with the widest range of mounting hardware common to industrial automations applications. With EZ-Light's compact, unobtrusive size and mounting flexibility, it is easier to install indicator lights and locate them near the equipment operator.

Adding to the flexibility of the EZ-Light are its Euro-style quick-disconnect connector options. "With no messy soldering, incorporating an EZ-Light into an application is as easy as plugging in a sensor," said Chris Dales, Banner product design specialist. "Multiple threaded mounting sizes make EZ-Lights possibly the easiest to use indicator light available on the market today."

Applications

With their compact size, rugged sealed construction, indication flexibility and easy installation, these indicator lights are suitable for nearly any process or machinery status application. Example applications include the following:

* Indicating machine status modes including RUN, STOP, RESET, ALERT, READY, WARNING.

* Indicating PASS and FAIL for part manufacturing or process monitoring.

* Providing visual illumination for pick-to-light and bin assembly.

* Providing larger, operator-friendly safety indications on machinery.

Specifications and features

Rugged and compact EZ-Light models are rated IP67, oil- and water-tight with Euro-style QD connectors that require no soldering. All models are compatible with PLC or other logic-level control outputs. Easy-to-install mounting brackets are available along with a number of quick-disconnect QD cable lengths.

* EZ-Light 3-colour general-purpose models feature red/yellow/green multifunction display standard with optional custom LED colours. Available in nickel-plated brass 18 mm barrels or thermoplastic 18 and 30 mm T-style right-angle models. 10 to 30 V d.c. general-purpose EL-Lights are available to receive NPN or PNP inputs depending on model.

* EZ-Light 7-function models offer the ability to illuminate in multiple colours and feature preconfigured flashing sequences. Available in nickel-plated brass 18 mm barrels or thermoplastic 30 mm T-style right-angle configurations. 10 to 30 V d.c. 7-function EZ-Lights require a PNP input.

* EZ-Light for EZ-Screen provides a large, remotely located red/green indicator for use with EZ-Screen safety light screens. Available in nickel- plated brass 18 mm barrels or thermoplastic 18 and 30 mm T-style right-angle models. EZ-Lights for EZ-Screen are designed to interface directly with an existing EZ-Screen system through the use of an 8-pin 'Y' splitter cable.
