4-20
mA current transmitter for platinum 100-ohm RTD (alpha =
0.00385). Standard features include field-selectable zero
and span, output protection to 120 Vac, two-or three-wire
operation, input-to-output isolation, operation from 9 to
50 Vdc loop power, -40 to +85°C operating temperature, waterproof
die-cast metal housing, screw-terminal barrier strip. For
surface mount, 63.5 mm (2.50 in) relay track or for use
with MXS1 and explosion-proof housings. Default calibration:
0 to 850°C = 4-20 mA. |

Custom
scaling for standard non-linearizing 501. For use with variable
resistance sources, specify ohms for 4 mA and 20 mA. Minimum
span is 35 ohms, maximum span is 400 ohms, maximum zero
offset is 365 ohms. For use with RTDs, specify metal and
alpha of the RTD, and temperatures for 4 mA and 20 mA output. |
