Description

Removable screw-clamp connector for Laurel transmitters Micron LTA Series 4-20 mA output transmitters duplicate the performance and extensive programmable features of their Micron digital panel meter, counter and timer counterparts. This allows unique configurations, such as 4-20 mA transmitter versions of pulse totalizers, analog totalizers, or quadrature position meters. A unique product is Micron's TS6 serial-to-analog converter transmitter, which converts serial data to an isolated analog output.

Easy transmitter programming is via Micron's Instrument Setup Software, which runs on a PC under MS Windows. This software can be downloaded from this website at no charge. The required transmitter-to-PC interface cable is available from Micron (P/N CBL04). The transmitters convert the analog signal into an internal digital reading from -99,999 to +99,999 counts for analog signals and -999,999 to +999,999 counts for pulse signals. Specific readings in counts are then assigned to the desired minimum and maximum analog output. Multiple calibration methods are selectable for use with or without an external calibration reference.

Three analog outputs are jumper selectable: 4-20 mA, 0-20 mA or 0-10V. All selections provide 16-bit (0.0015%) resolution of output span and 0.02% output accuracy. Output isolation from signal and power grounds eliminates potential ground loop problems.

Fast read rate at up to 50 or 60 conversions per second while integrating the signal over a full power line cycle is provided by Concurrent Slope (Pat 5,262,780) analog-to-digital conversion for analog input signals. High read rate is ideal for peak or valley capture and for real-time computer interface and control. Digital signal filtering modes are selectable for stable readings in electrically noisy environments. The internal digital readings and analog output can be individually selected to be either unfiltered or filtered.

Standard features LTA Series transmitters include:

Analog transmitter output, 16-bit, user scalable and isolated. User selectable 4-20 mA, 0-20 mA or 0-10V levels.
Serial communications, isolated. User selectable RS232 or RS485, half or full duplex, Modbus or Micron ASCII protocol.
Dual solid state relays for control or alarm, isolated. Rated 120 mA at 130 Vac or 170 Vdc.
Universal AC power supply for 85-264 Vac.
