Description Laureate 4-20 mA output, process input transmitters provide six DC voltage ranges and four DC current ranges for use with a wide range of industrial transducers whose output requires zero and span adjustment. All ranges are factory calibrated and jumper selectable. The two most sensitive voltage ranges, 200 mV and 2V, provide a high input impedance of 1 Gohm to minimize the load on the voltage signal. With Laureate process transmitters as described in this web page, strain gauges with a 20 mV output can be internally scaled to display up to 10,000 counts, while outputs of 200 mV can be scaled to 99,999 counts. With Laureate load cell transmitters, strain gauges with a 20 mV output can be internally scaled to the full 99,999 counts. Laureate process input transmitters duplicate the performance and programmable features of their Laureate process digital panel meter counterparts. Features include exceptional accuracy at high read rate, and optional dual solid state relays for local alarm or control. The transmitters are housed in a DIN rail case that is only 22.5 mm (0.89") thick. Signal connections are via detachable screw terminal connectors. In addition to the 4-20 mA output that would typically be used for signal transmission in an industrial environment, a 0-10V analog output is selectable. Either output tracks an internal digital reading, which is accurate to within ±0.01% of full scale input and is scalable in software. Output resolution is set by a 12-bit (4096 step) ultralinear digital-to-analog converter (DAC). Overall process transmitter accuracy is set by the DAC to ±0.05% of output span. Output isolation from signal and power grounds is provided by a separate on-board transmitter power supply, thereby eliminating potential problems caused by ground loops. The supply can an drive 20 mA into a 500 ohm (or lower) load for 10V compliance, or 10V into 5K ohm (or higher) load for 2 mA compliance.Transmitter programming is via a three-terminal RS-232 port using Laurel's PC-based Instrument Setup Software. This software can be downloaded from this website at no charge. The required transmitter-to-PC interface cable is available from Laurel (P/N CBL03). |
