1229a Frequency Generator
-
Precise Time and Frequency, Inc.
The ptf 1229A utilizes the latest technological advances in precision frequency synthesizers to provide a multiple output, wide range, high precision frequency reference instrument, capable of delivering frequencies over the range of 0.1Hz up to 30MHz with a resolution of 0.1 Hz over the full range.The unit includes an external reference input to allow extremely high accuracy outputs at precisely the frequency required, together with a front panel indicator to verify “lock” to the external reference. The standard unit includes two independent frequency outputs of any frequency within the range, and provides both sine and square wave outputs for each frequency.An expansion module gives the capability to increase the number of independent frequency outputs up to a total of four frequencies, with sine and square wave outputs for each, giving a total of eight outputs.

5 Digit Frequency Meter
CS2-F
-
CS2-F Freqeuncy Meter is designed high accuracy measurement, display, control and communication (Modbus RTU mode) of pulse(Frequency) or AC Frequency.● The innovation feature is auto-range input from 0.01Hz~ 100KHz(~140KHz in option). The display resolution will be auto-changed to show the highest according to input frequency. They are also building in 4 Relay outputs, 3 External Control Inputs, 1 Analogue output and 1 RS485(Modbus RTU Mode) interface with versatile functions such as control, alarm, re-transmission and communication for a wide range of testing and machinery control applications. Please refer to the detail description on pages 2/33~7/33.There are not only controllers, but also an I/O interface in any system. ADtek built in difference ideal for External Control input and Relay output as like as I/O module of PLC. It’s very connivance to achieve remote monitoring and control by CS2 series.

SparkFun Coulomb Counter Breakout
LTC4150
-
Odometers are extremely useful for cars, they tell you how far you have gone, wouldn't it be nice if you were able to have a device that does the same for electrical current? The LTC4150 SparkFun Coulomb Counter Breakout is here to be your odometer for current. If you are wondering: a coulomb is defined as, to put it simply, one amp for one second. This breakout is capable of constantly monitoring the current your sensor is using, is able to add it up, and will give you a pulse each time a given amount of amp-hours have been used. When used effectively and if you start with a full battery, you’ll always know exactly how much of it is left!
