Signal Converter Type


	Signal Converter Type
	Your choices are...
	Analog-to-Digital Converter		Analog-to-digital converters or A/D converters (ADC) sample analog signals and convert them to a series of digital values to represent the signal to a computer processor.
	Digital-to-Analog Converter		Digital-to-analog converters or D/A converters (DAC) are electronic device, often an integrated circuit that converts a digital number into a corresponding analog voltage or current.
	Frequency Converter / Translator		Frequency converters or translators converts or scales the input frequency to the desired output frequency value.
	Voltage Converter / Inverter		Voltage converters or inverters accept voltage inputs and provide scaled voltage outputs. Conversion types include scaling-up a low-level signal, voltage doubling, and inversion (i.e., converting a positive voltage to negative and vice versa).
	Frequency-to-Voltage Converter		With frequency-to-voltage converters, an analog voltage output is a function of the input signal frequency.
	Voltage-to-Frequency Converter		With voltage-to-frequency converters, the output signal frequency is a function of the input signal voltage. Output types include sine wave, pulse train, or pulse width modulation (PWM).
	Current-to-Voltage Converter		With current-to-voltage converters, the output signal voltage is a function of the input current.
	Current Loop Converter		Current loop converters are designed to convert an analog or digital signal to a current loop output such as 4-20mA or 0-20mA.
	Charge Amplifiers/Converters		Charge converters are designed to convert the charge output from a piezoelectric or other charge-producing sensor to a signal such as analog voltage or current.
	Other		Other, unlisted or specialized signal conversion or conditioning function.

Signal Converter Performance


	Analog Input Channels:		This is the maximum number of analog channel inputs. The single-ended number is specified when single-ended inputs are available as twice the number of differential inputs. Differential channels use the difference between two signals as an input; common mode is filtered out. In some systems, differential inputs are combinations of two single-ended inputs. When this is the case, twice the numbers of differential channels are available as single-ended inputs.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Differential Channels		Differential channels have two inputs. The signal to process is the voltage (V) difference between the two inputs. For example, if one reading is 4.93 V and the other reading is 5.16 V, the meaningful value is the 0.23 V difference between the two. Often, this applies to precision measurements where the difference between two low voltage inputs is small but critical.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Resolution		Resolution refers to the degree of fineness of the digital word representing the analog value. A ten-bit number contains 2¹⁰, or 1024, increments. A 0-10V signal could therefore be resolved into approximately 0.01V increments. A 12-bit representation would be in 2¹² (4096) increments, or divisions of 0.0024V for the same signal. Each additional bit doubles the resolution, and one bit is required for the polarity (sign) of a number.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Accuracy		Accuracy depends on the signal conditioning linearity, hysteresis, temperature considerations, etc. It is represented here as percent full scale of measurement range.
	Search Logic:		All matching products will have a value less than or equal to the specified value.

Signal Converter Package



	Your choices are...
	Printed Circuit Board (PCB)		Devices are printed circuit boards (PCBs) that attach to enclosures or plug directly into computer backplanes.
	Panel / Chassis Mount		Devices attach to a panel or bolt onto a chassis.
	Modular Bay / Slot System		Devices stack in modular bays or slots and can be interfaced to other units.
	Rack Mount		Devices are rack-mounted and fit inside enclosures such as a standard 19” telecommunications rack.
	DIN Rail		Devices mount on a standard DIN rail. DIN is an acronym for Deutsches Institut für Normung (DIN), a German national organization for standardization.
	Stand Alone		Devices are benchtop or floor-standing units with a full casing or cabinet and an integral interface.
	Other		Other unlisted form factors.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	User Interface:
	Your choices are...
	None		There is no user input or programmability. Instead, there is "black box" style of storage for download or processing elsewhere.
	Front Panel and Display		There are integral controls, a keypad, and/or display on the panel of the unit.
	Touch Screen		The device's visual display screen is contact-sensitive to allow direct input.
	Hand-held / Remote Programmer		The interface unit is designed specifically to be held in the hand while the user enters program parameters, and may include remote programming.
	Computer Programmable		The device is interfaced to a separate supervisory or host computer.
	Other		Other unlisted user interface methods.

	Your choices are...
	DC Voltage
	AC Voltage
	DC Current
	AC Current
	Frequency		Input for varying frequency, pulse, or other specialized waveform.
	Charge		Charge is the output of a piezoelectric device. A charge signal typically requires filtering and amplification.

	Integral Filter?		Integral filters allow certain signal frequencies to pass while attenuating others. These filters can also operate on signal phase.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Integral Amplifier?		Amplifiers multiply a signal to the matching scale of the input device. Amplifier gains, or multiplication factors, may be greater than one or fractional for signal reduction.
