4.6.2 Power supply
4–20 mA HART (option code S)
Transmitter operates on 10.5–42.4 Vdc at the terminal of the transmitter. The dc power
supply should provide power with less than two percent ripple. A minimum of 16.6V is
required for loops with a 250 Ω resistance.
Do not run signal wiring in conduit or open trays with power wiring or near heavy electrical
equipment.
If all connections are not sealed, excess moisture accumulation can damage the
transmitter. Make sure to mount the transmitter with the electrical housing positioned
downward for drainage. To avoid moisture accumulation in the housing, install wiring with
a drip loop, and ensure the bottom of the drip loop is mounted lower than the conduit
connections of the transmitter housing.
