Unit Specifications
   Number of Functions       
   Your choices are...         
   Single Function       The unit has only one function.   
   Multi-function       The unit can be setup or programmed for more than one function. 
   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.
   Functions       
   Your choices are...         
   Arithmetic Functions       The counter / timer can be programmed to perform simple or complex arithmetic functions. These arithmetic functions may include the sum, difference, multiple, square root, etc. 
   Batch Counter       Batch counters count UP only and are usually pre-settable so that when the required number of batches or pieces has been completed, the process can stop automatically. 
   Controller       Controllers have outputs to regulate or control equipment based on sensor inputs or preset limits. 
   Count Totalizer       Generally, counters can accumulate counts but cannot control a machine. Some totalizers are pre-settable, but their primary function is to keep track of counts over a relatively long period of time. 
   Event Counter       Even counters are units that count the occurrences of a certain condition. 
   Frequency Counter       Frequency counters are units for displaying frequency, the number of cycles per second of a waveform. The unit of frequency is Hertz (Hz). 
   Position Indicator       Position indicators can accept, process, and display angle or travel data. 
   Preset       Preset counters (or predetermining counters) can control an external circuit when its counted total matches user-entered preset limits. Electronic models are the most versatile and offer high performance at a relatively low price. Mechanical and electrical types offer simplicity of installation and operation.  Preset mode is a counting mode where counting is generally subtractive. The counter resets or auto-recycles to the preset count. When the counter counts to zero, the output associated with the preset number occurs. 
   Pulse Counter       Pulse counters are used to count a momentary but sharp change in current and voltage. Count pulses include square waves and rectangular waves. Pulses are digital signals; the voltage or current is either "on" or "off." 
   Counter / Timer Combination       Counter / timer combinations can perform both counting and timing functions. 
   Other       Other unlisted, specialized, or proprietary configuration.

   Bi-directional Counter       The counter can move forward or backward (UP or DOWN) in its counting sequence. 
   Other       Other unlisted, specialized, or proprietary directions.

   Manual       Reset is performed through a manual knob or lock-and-key reset. 
   Remote       The unit can be reset remotely by a switch or computer interface. 
   Auto Reset       Auto reset is a controller feature that continuously compensates for droop by integrating errors over time and adjusting the proportional band appropriately.

   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       A format that uses continuous physical variables such as voltage amplitude or frequency variations to transmit information. 
   Mechanical Switch / Relay         
   Solid-state Switch / Relay       A solid-state switching device with no moving parts that switches current on and off.

   Ethernet       A local-area network (LAN) protocol developed by Xerox Corporation in cooperation with DEC and Intel in 1976. Ethernet uses a bus or star topology and supports data transfer rates of 10 Mbps. The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. Ethernet uses the CSMA/CD access method to handle simultaneous demands. It is one of the most widely implemented LAN standards.
