Input Channels


	Number of Inputs		The number of inputs is the total number of signals sent to the controller. This number includes process variable signals such as temperature, pressure, level, speed, etc., and status inputs such as on/off.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Generic Inputs
	Your choices are...
	Pulse (Frequency)		The computer accepts a magnetic pickup or direct current (DC) pulse input.
	Analog Current		The computer accepts an analog current, typically 4-20 mA.
	Analog Voltage		The computer accepts an analog voltage, e.g. 0-10 Vdc.
	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.

	Flow Sensor Inputs
	Your choices are...
	Differential Pressure Meters		Differential flow meters obstruct the fluid flow to create a differential pressure (DP) that can be measured indirectly. The DP is related to the square of velocity.
	True Mass Flow Meters		True mass flow meters measure the rate of flow directly. Products include thermal meters and Coriolis meters.
	Velocity Meters		Velocity meters are pulse or analog devices which operate linearly with respect to volumetric flow rate. Products include turbine meters, electromagnetic meters, vortex meters, ultrasonic meters, etc.
	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.

	Additional Process Inputs
	Your choices are...
	Density		Devices can determine mass flow rates from volumetric readings.
	Temperature		Devices are designed for temperature measurement or compensation.
	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.

Output Channels


	Number of Control Outputs		The number of control outputs is the total number of outputs used to control, compensate or correct the process. This number includes analog control outputs, as well as relays and switches which activate or deactivate control devices.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Electrical Outputs
	Your choices are...
	Analog Voltage		Any analog voltage output. Output voltage is a simple (usually linear) function of the measurement.
	Analog Current		Often called a transmitter. A current is imposed on the output circuit proportional to the measurement. Feedback is used to provide the appropriate current regardless of line noise, impedance, etc. Useful when sending signals over long distances.
	Frequency / Pulse		Frequency or modulated frequency output (Ex. sine wave, pulse train, AM, FM)
	Switch		Flow triggers a switch output based on preset flow rates.
	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.

Mounting Configuration



	Your choices are...
	Mounts on Flow Sensor		Mounts directly on flowmeter for local indication, may also be called field mount or in-line.
	Panel Mount		The device can be placed into, or through, a depression within an existing panel so that its face is flush, or nearly flush, with the panel.
	Wall Mount		The device is designed specifically to be attached against a wall. The method of attachment may include screws, bolts, rails, flanges, etc.
	Laboratory Bench / Portable		Common configuration for lab and test units.
	Rack Mount		The device is designed to be mounted directly into a rack. It comes equipped with the necessary rail guides, flanges, or tabs to be mounted in this fashion. The standard 19" rack is typical of this style.
	DIN Rail Mount		The device is designed to be mounted on a standard DIN rail.
	Other		Other unlisted, specialized, or proprietary configuration.
	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.

Features
