NEW Nidec-SHIMPO PC-FR Process Counter Totalizer

Shimpo Instruments, A Division of Nidec-Shimpo America Corp., has released its new PC-FR 1/8 DIN Process Counter/Totalizer, designed for process automation counting or totalizing applications. The PC-FR is a dual-channel frequency, rate and period counter or totalizer that accepts inputs from contact relays or proximity and magnetic sensors that produce one of the following outputs: PNP/NPN, TTL or CMOS logic, contact closure, or AC signals from 12 mV to 250 V ac. Each channel (A or B) may be independently set up and scaled to count up from zero or a set value to a preset limit, or down from a set value to zero or limit. Either channel can easily be displayed via a front panel pushbutton.

The PC-FR Counter/Totalizer comes with a versatile, decimal point adjustable 6 digit display capable of any value from +/-999,999 for frequencies ranging from 0.005 Hz to 1 MHz, rates in various engineering units and period (inverse of frequency). The scaling function allows direct readout in any engineering unit such as gallons or cubic feet sensed from a turbine flow meter, or the ability to show the total quantity of containers in cartons detected on a conveyor from an optical sensor. Totaled values are stored in non-volatile memory enabling retention in the absence of power.

Available extended models can provide rate and total simultaneously with one channel displaying total while the other displays process rate. This mode is ideal for flow applications when the same signal is applied to both channels. Included with extended models are several arithmetic functions such as A+B, A-B, AxB, A/B and A/B-1 (draw). For example, A+B allows two input flows to be summed for total flow, while A-B allows outflow to be subtracted from inflow for a net flow result. If transducers with a frequency output are used, AxB allows horsepower to be displayed based on measured torque and RPM or based on force and velocity. A/B can be used for the proper mixing of ingredients, while A/B-1 (draw) is used to compare rates for stretching or tensioning.

The PC-AN's offer Universal AC or DC power selections which enables flexibility with usage in various power situations. Optional 8 A contact or 120 mA solid state relay outputs, plus an analog process signal output with 4 user-selectable current or voltage ranges are available. To provide a higher level of communication and integration into a system's network, several communication protocols such as RS-232, RS-485 and even USB options are available. Units come standard with an isolated excitation output to power transducers, eliminating need for additional power supply.

The excellent offering provided by the PC-FR Process Counter/Totalizer make them ideal in various applications such as the display of AC line frequencies to 250 V ac, RPM monitoring, speed detection from proximity switches and flow rate from turbine meter inputs down to 12 mV.
