Form Factor


	Form Factor
	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 in. 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.

Device Specifications


	Maximum Frequency:		The highest frequency the converter will accept.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	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.

Signal Inputs


	AC Voltage Input?
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	AC Current Input?
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Specialized & Other Inputs


	Encoder Input?		Inputs for an encoder signal such as binary, gray, or binary-coded decimal (BCD).
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Counter / Tachometer Input?		Typically, the inputs from counters or tachometers are one signal per cycle counts.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Timer / Clock Input?		Inputs for any type of time signal.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Relay / Switch Input?		Inputs for a discrete, on/off signal from an exterior device.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Other Input?		Other unlisted or specialized inputs.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Environment


	Operating Temperature		Full required range of ambient operating temperature.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

	Vibration Rating		Maximum vibration that the device can withstand and still meet performance specifications.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Shock Rating		Maximum shock that the device can withstand and still meet performance specifications.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
