| Description: |
...The T773 isolating two-wire transmitter has 5 input ranges and 2 output ranges, all of which arefield selectable via top-accessed DIP switches. The T773 can accept square, triangle or pulsewaveforms up to 18KHz with amplitudes from 10mVrms to 35V peak-to-peak. The T773 provides1000Vrms of transformer-coupled isolation with outputs of either 4-20mA or 10-50mA. Current... ...300Hz (e.g., 300Hz to 1000Hz).ApplicationThe T773 is useful in any application requiring isolation of a 2-wire loop current from a pulse outputtransducer, such as a magnetic pickup or a turbine flowmeter. The output of the T773 can be used... ...The T773 has 30% zero “turn-up” and 80% span “turn-down” adjustments within any user-selectedinput range. For example, Range 3 of Table 1 specifies 0 to 2100Hz with a minimum span of 420Hz(2100Hz - 420Hz = 1680Hz, or 80%). This 80% adjustability allows the user to field calibrate theunit for the maximum range of 0 to 2100Hz down to the minimum range of 0 to 420Hz. The maximum... |
