376B Series Digital Counter

The 376B is available as a Single Preset or a Dual Preset Counter. The Dual Preset Counter can be set as a Batch Counter. Both the Single Preset and the Dual Preset versions have an internal Totalizing Counter which will accumulate counts over numerous cycles. The 376B can be set up for IntervalHIGH SPEED COUNTING: The Single Preset 376B counts at a maximum frequency of 10 kHz. In addition to its high speed capabilities, a debounce circuit can be enabled to limit the count frequency to 100 Hz.COUNTING MODES: The 376B is available as a Single Preset or a Dual Preset Counter. The Dual Preset Counter can be set as a Batch Counter. Both the Single Preset and the Dual Preset versions have an internal Totalizing Counter which will accumulate counts over numerous cycles. The 376A can be set up for Interval Counting Mode using a separate Start Signal, and can also be set up for Count with Inhibit Mode.INPUTS/OUTPUTS: Two count inputs are available with the 376B. These inputs can be set to count Uni-and Bi-directionally. They can also be set to accept Quadrature inputs and can multiply the quadrature signals X1, X2 and X4. Input 2 also operates as the Start input in Interval Mode and as the inhibit input in Count with Inhibit Mode.These two inputs can be set to accept Current Sinking or Sourcing signals, and there is a High/Low Threshold Bias setting allowing the input of TTL level signals.Two types of outputs are available. The Relay outputs are rated for 10 A at 250 VAC and 30 VDC. The NPN Transistor outputs are current sinking and are rated for 100 mA at 30 VDC. These outputs are field replaceable. Each output can be set to either Latch ON, Remain ON for a Time Delay, or turn OFF at a Preset.SCALE FACTOR: A Prescale value can be set which allows the operator to view and set counts using real units of measure. The Prescale value is a multiplier which is applied to the count inputs to determine the display and preset values. The Prescale value can be set from 0.00001 to 9.99999. The 376B also allows setting of the decimal point position in any of 6 positions.RESETTING THE COUNTER: The Counter can be reset using the Reset key on the panel or by using the external Reset Inputs. There are three current sinking external inputs. Each one is dedicated to resetting the Process, Batch and Totalizing Counters. In addition, the 376B can be set to either retain its count or reset upon power failure.
