Splashproof Cover
Model IPC
Model IPC Splashproof Cover adds protection to IP67 / NEMA-4X from the front panel. It fits all of Laurel's 1/8 DIN instruments as well as 1/8 DIN instruments by other manufacturers, provided that instrument dimensions in front of the panel do not exceed 48 x 96 x 15 mm (1.89" x 3.78" x 0.59").

Laureate Duty Cycle Meter
Model FRD
Configured display ON or OFF period as a percentage of total period over a gate time from 10 ms to 199.99 s. A resolution of 1%, 0.1% or 0.01% is selectable. Ideal for repetitive short pulses with a pulse width down to less than 1 s.

Modbus or Laurel ASCII ProtocolSerial Output DIN Rail Transmitters
Laureate TM Series serial output transmitters can be jumpered for two signal levels: RS232 or RS485. Two serial protocols are selectable in software: Modbus or Laurel's Custom ASCII.Modbus protocol operation is fully compliant with the Modbus Over Serial Line Specification V1.0 (2002) for 2-wire, half-duplex connection.

Batch Controller (pulse input)
A low-cost controller for repetitive fill operations. The typical application utilizes a flow meter input and two built-in relays: a Prewarn relay slows down the pump near a preset to avoid overshoot and a Batch relay stops the pump at the preset.
-
product
Batch Controller (analog input)
Same capabilities as the Laureate pulse-input batch controller, but for 0-1 mA, 4-20 mA, or 0-10 V process signals, as made possible by a built-in voltage-to-frequency (V-to-F) converter. Square root extraction is standard for use with flow meters.

Digital Panel Meter
DC
Laureate DC voltage and current panel meters with a DC signal conditioner board combine high accuracy with high read rate and a wide range of isolated output options for computer interface and control. Accuracy is 99.99% of full scale 1 count. Used as a direct-reading DC voltmeter, the Laureate provides a full-scale readout of 20,000 counts and six full-scale voltage ranges from 200.00 mV with 10 mV resolution to 600.0 V with 100 mV resolution.

product
Quadrature Position & Rate Meter
Accepts low-level differential or single-ended 5 V logic level quadrature signals from shaft encoders to display scaled position or scaled rate. One, two or four transitions may be counted at a maximum combined rate of 250 kHz and be mathematically scaled to display in engineering units from -999,999 to +999,999. An analog output scaled to the display and relay outputs are optional.

A+B, A-B, AxB, A/B, A/B-1 Draw Meter
Arithmetic functions (+, -, /, x) on dual channels A and B open a world of possibilities. For example, add or subtract rates from two flow meters for combined scaled flow or volume. Display the ratio of flow rates, RPM of rollers, or speed of moving belts. Draw, which is obtained by subtracting 1 from ratio, can be used to indicate elongation or shrinkage of material as it passes between rollers.

1/8 DIN Bargraph Process Display
BAR Series
30-segment bar graph meter with 75 mm (3") scale length for 4-20 mA, 0-1 mA, 0-10V, or 1-5 V signals. Optional dual-relay output.

product
Duty Cycle Meter
Displays ON or OFF period as a percentage of total period over a programmed gate time from 10 ms to 199.99 s. A resolution of 1%, 0.1% or 0.01% is user-selectable. Applications include monitoring modulated proportional control systems and pulse-modulated systems, such as radar, lasers or packet radio.

product
Digital Stopwatch
Designed to time single events or processes which produce start and stop pulses. Resolution to 0.2 s, duration from 1 s to 999,999 hours. Time may be displayed in HH.MM.SS clock format with 1 s resolution or in decimal H, M or S format with six-digit resolution. Multiple events can also be accumulated.

Wall-Mount Enclosure
Model BOX
Model BOX is a wall-mount / bulkhead enclosure which provides environmental protection to IP65 / NEMA-4X. It comes with a 1/8 DIN panel cutout (45 x 92 mm) and can be used with 1/8 DIN instruments with a depth up to 134.5 mm (5.30"). This includes all 1/8 DIN instruments sold by Laurel Electronics.

product
Process Totalizer (analog input)
Displays and totalizes 0-1 mA, 4-20 mA, or 0-10 V process signals. Square root extraction is standard for flow applications, allowing display of volume from the 4-20 mA signal of a flow transducer with a linear or squared output.
-
product
Totalizer (pulse input)
Two independent scalable pulse-input channels. Count up or down to a preset at rated up to 1 MHz. Scaled rate and total from the same electronic counter. Scaling for direct readout in engineering units, such as gallons or cubic feet based on counts from a turbine flow meter. One channel can display total while other displays rate.
