A 16-bit analog output option board can turn a Laureate 1/8 DIN digital panel meter, counter, timer or remote display into a superb, isolated, linearized transmitter or signal conditioner with exceptional accuracy and high-speed response. The analog output for thermocouples, RTDs and custom curves is linearized to the displayed reading.

Single-output and dual-output versions of the analog output option board are available for use with Laureate counter-timers and the Laureate 6-digit remote display.

• With the single-output version, the output can be selected as 4-20 mA, 0-20 mA, unipolar 0-10V, or bipolar -10V to +10V with a 20V span. If a voltage output is selected, output pins 1 and 2 may be reversed to provide reversed polarity.

• With the dual-output version, either output can be selected as 4-20 mA, 0-20 mA, or unipolar 0-10V. The ground of the two outputs is shared. One of the outputs is typically be tied to the displayed item, while the second output may be tied to a non-displayed item. For example, with the Extended Laureate frequency meter, Item #1 can be assigned to rate, while Item #2 is assigned to total. With the Laureate batch controller, Item #1 is the current batch total, Item #2 can be assigned to grand total or number of batches, and Item #3 is the flow rate.

A 16-bit D-to-A converter provides 0.0015% full-scale resolution and ±0.02% full-scale accuracy. The update rate for meters is a fast 60/sec for 60 Hz power or 50/sec at 50 Hz power. The analog output can track the unfiltered signal for fastest response, or a digitally filtered signal for best noise rejection.

Laureate DIN rail transmitters, whether 4-20 mA transmitters or serial output transmitters, also come with a scalable 16-bit analog output, which can be configured for current or voltage.
