Laurel Electronics Laureate 1/8 Din Digital Panel Meter, Basic Dpm With Red Leds, Universal 85-264 Vac Power, No Relays, No Analog Output, No Communication Option, Load Cell Input, 6-Wire Ratio, Custom Scaled Display Rohs Compliant: Yes - L20000WM1

Model L20000WM1 by Laurel Electronics is a load cell and DC microvolt meter which includes a load cell and microvolt signal conditioner, 4 or 6-wire ratio, with customer specified scaling, universal 85-264 Vac or 95-300 Vdc power, and five red 14.2 mm (0.56 inch) LED digits. DC microvolt meter operation provides sensitivity down to +/-20 mV full scale with 1 µV resolution. A moving average digital filter assures quiet readings in electrically noisy environments. Zero and span may be scaled from 0 to +/-99,999. Meter accuracy is 0.01% of full scale +/- 2 counts. Custom curve linearization, available with the optional Extended main board, can extend the working range of load cells. An isolated 5, 10 or 24 Vdc isolated excitation output is standard and can power up to four 350-ohm load cells in parallel at 10V. The meter operates in a ratiometric mode to eliminate errors due to excitation variations. When excitation sense inputs are used in 6-wire connection, the meter compensates for variation in resistance of the transducer leads, thereby allowing long cable runs. High read rates at up to 60 or 50 conversions per second are ideal for peak or valley capture, real-time computer interface, and control. Peak and valley values are automatically captured. Modular architecture provides a choice of power supply boards, relay boards for alarm or control, analog output boards, and communication boards. Available communication boards include RS232, RS485, USB and Ethernet. The Modbus protocol is fully supported as is the simpler Custom ASCII protocol. Power and all inputs and outputs are mutually isolated. The meter fits in a 1/8 DIN panel cutout (92 x 45 mm) and is protected to NEMA 4X (IP65) when panel mounted. It is certified to CE, RoHS, and ETL / UL standards.
