Universal IV™ CM Density Compensated Model
2.2.5.2 (4-20mA) HART 7.0 Signal Loop Wiring
Due to the low power consumption of the instrument, the wiring need only be light gauge
(e.g. 20 AWG shielded twisted pair) for the 4 – 20 mA signal loop. Shielded twisted pair
cables are recommended. Supply Voltage requirement is 19-30VDC. Minimum loop
resistance for HART® communications is 250 Ω. Minimum 19V @ 22mA is required
at the 4-20mA input terminals.
*Shield wire may be "Grounded" at the identified housing screw or cut depending on
the power configuration
