Signal Converters Specifications

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 number 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...
	Integrated Circuit (IC)		Devices are integrated circuit (IC) chips that mount on printed circuit boards (PCBs).
	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		No user input or programmability; "black box" style of storage for download or processing elsewhere.
	Front Panel & Display		Integral controls, 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		Interface unit specifically meant to hold in hand while entering program parameters; may include remote programming.
	Computer Programmable		Device is interfaced to a separate supervisory or host computer.
	Other		Any unlisted user interface method.
	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.

Signal Converter Features


	Signal Inputs
	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.
	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.

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

	Signal Isolator		Signal isolation is the separation of any direct electrical contact of a signal. This can be done in various ways including optical isolation, capacitors, and magnetic induction.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Multiplexer		Handles several inputs and serially combines them into one output for transmission. Some multiplexers perform the reverse function.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
