Model LTE80FR includes:

Model LTE62QD DIN rail transmitter by Laurel Electronics has Dual channel pulse or AC inputs configurable for frequency, rate, totalizing, timing, custom curve linearization, arithmetic functions (A*B, A/B, A+B, AB, A/B1), phase angle, duty cycle, up/down counting, batch control., Ethernet I/O plus 420 mA or 010V analog output and dual relays. The model is configured for Extended main board and Universal 85264 Vac power. It can be programmed for frequency, rate, period, totalizing, timing, arithmetic functions, batch control, AC phase angle, AC power factor, and duty cycle. The Laureate dualchannel frequency, rate and period transmitter is for frequency from 0.005 Hz to 1 MHz, rate in engineering units, or period (inverse of frequency). Values can range to 999,999 counts. Applications include the accurate transmission of AC line frequency, RPM, speed from proximity switch inputs, and flow from turbine flow meter inputs. The Laureate counter determines frequency by timing an integral number of periods over a specified gate time, and then taking the inverse of period. The Laureate dualchannel up or down totalizer may be independently set up and scaled to count up from zero (or other value) to a preset limit, or to count down from a preset value to zero (or other limit). Countdown operation is set up by entering a negative scale factor. The totalizer can display values from 999,999 to 999,999 with a programmable decimal point. Scaling allows direct readout in engineering units. Totals are stored in nonvolatile memory so as to be retained in the absence of power. The Laureate stopwatch transmitter times single events which produce start and stop pulses. It can also time the width of a single pulse. Highest resolution is 0.2 us. The event time may be displayed H, M or S format with sixdigit resolutionor or in HH.MM.SS clock format with 1 s resolution. The stopwatch display is updated during timing. Accumulated time from multiple events is also tracked and may be displayed to 999,999 hours. The Laureate AtoB Time Interval Meter can display pulse width or time delay between individual pulses to a resolution of 0.2 µs. It can also display average pulse width or average time delay between multiple pulses. Time interval is measured between inputs on channels A and B. Time interval can be displayed in seconds, milliseconds, or microseconds with 6digit resolution. Arithmetic functions A+B, AB, AxB, A/B or A/B1 track the sum, difference, product, ratio, or draw of two input channels. Arithmetic operations can be applied to scaled rates, scaled totals, square root of rates, totals after square root extraction, custom curve linearized rates, or totals after custom curve linearization. The phase angle transmitter tracks the phase lead or lag in degrees between two periodic signals of the same period. The power factor of an AC power system is the ratio of real power in watts (W) divided by apparent power in voltamperes (VA). The duty cycle transmitter tracks ON or OFF period as a percentage from 0% to 100% of total period of repetitive pulse trains. The FR dualchannel signal conditioner accepts inputs from proximity switches w ith PNP or NPN output, TTL or CMOS logic, magnetic pickups, contact closures, lowlevel outputs from turbine flow meters down to 12 mV, and highlevel AC line inputs up to 250 Vac. A builtin isolated 5, 10, or 24 Vdc excitation supply can power proximity switches and other sensors, thus eliminating the need for an external power supply. Three analog output transmitter settings are jumper selectable: 420 mA, 020 mA or 010V. The output tracks the reading up to 99,999 counts that would be transmitted digitally. Output isolation from signal and power grounds eliminates potential ground loop problems. The supply can drive 20 mA into a 500 ohm (or lower) load for 10V compliance, or 10V into a 5K ohm (or higher) load for 2 mA compliance. Standard features of Laureate transmitters include:
