Transducer excitation output, isolated.Dual solid state relays, isolated, for alarm or control.The Laurel ASCII protocol is simpler than the Modbus protocol and is recommended when all devices are Laureates. Modbus operation is fully compliant with Modbus Over Serial Line Specification V1.0 (2002). Three protocols are user selectable: Modbus RTU, Modbus ASCII, or Laurel ASCII. Serial communications output, RS232 or RS485 (half or full duplex), jumper selectable.Output isolation from signal and power grounds eliminates potential ground loop problems. All selections provide 16-bit (0.0015%) resolution of output span and 0.02% output accuracy of a reading from -99,999 to +99,999 counts that is also transmitted digitally. 4-20 mA, 0-10V or -10V to +10V analog transmitter output, isolated, jumper-selectable and user scalable.Standard features of Laureate LT transmitters include: An Auto setting selects the time constant selection based on signal noise. When a significant change in signal level occurs, the filter adapts by briefly switching to the shortest time to follow the change, then reverts back to its selected time constant. An adaptive moving average filter selection provides a choice of 8 time constants from 80 ms to 9.6 s.

A batch average filter selection averages each 16 conversions for an update every 1/4 sec.

An unfiltered selection provides true peak and valley readings and aids in control applications.

With 6-wire load connection, it also compensates for lead resistance, allowing long cable runs.įast read rate at up to 50 or 60 conversions per second while integrating the signal over a full power line cycle are ideal for peak or valley capture and for real-time computer interface and control.ĭigital signal filtering modes are selectable for stable readings in electrically noisy environments. With 4-wire load connection, the transmitter operates in a ratiometric mode to eliminate errors due to power supply variations. Load cell connection can be via 4 or 6 wires. The unit's serial data output is accurate to ☐.01% of reading ☒ counts in ratiometric load cell mode and ☐.01% of full scale in ☒ counts in absolute microvolt meter mode.Ī built-in, isolated, 10V, 120 mA excitation supply can power up to four 350-ohm load cells in parallel. The selected input range for the full 0-20 mA output span can be as wide as ☙9,999 counts or as narrow as 150 counts, limited only by considerations of electrical noise and time constants of the programmable moving average digital filter. A most sensitive full-scale input range ☒0.000 mV can be scaled internally to ☙9,999 counts. The Laureate load cell or microvolt input transmitter is designed for use with load cells, strain gauges and microvolt input signals where exceptional sensitivity and stability are required.
