The 1018 PhidgetInterfaceKit 8/8/8 now has built-in hardware noise filtering on the Digital Inputs

Phidgets Inc. announced that he new version of the 1018 PhidgetInterfaceKit 8/8/8 now has a Digital Input Hardware Filter that eliminates false triggering from electrical noise. The digital input is filtered by a 2-stage filter, rejecting noise of higher frequency than 1Khz. This filter generally eliminates the need to shield the digital input from inductive and capacitive coupling likely to occur in wiring harnesses.

The 1018 is one of our most popular product and the addition of noise filtering on the Digital Inputs will make it a lot easier for the programmer to assess the validity of the data coming in. says Chester Fitchett, CEO of Phidgets.

The 1018 comes with:

· 8 Analog Inputs

· 8 Digital Inputs – with hardware noise filtering

· 8 Digital Outputs

The Analog Inputs are used to measure continuous quantities such as temperature, humidity, position, pressure, etc. Phidgets Inc. offers a wide variety of analog sensors that plugs directly into the 1018.

The Digital Inputs are used to convey the state of push buttons, limit switches, relays, etc.

The Digital Outputs can be used to drive LEDs, Solid State Relays, transistors, etc.

Software Environment

Unlike a lot of our competitor's products that require their users to write some firmware code in order to use their sensor, we are completely Plug and Play says Bernard Rousseau, Director of Marketing. With Phidgets, you plug it in and start using it and when it comes to programming, the user, not us, decides which operating system and which computer language he wants to use, added Rousseau.

Users can program Phidgets using a simple yet powerful and well documented Application Programming Interfade (API) that is supported under Windows (2000, XP, Vista), Windows CE, Mac OS X, and Linux. Users can write programs in Visual Basic, VB.NET, C#, C/C++, Flash/Flex, Java, Labview, Matlab, ActionScript 3.0, and Cocoa.

Phidgets also provides programming examples for all its products to help programmers write their own programs.
