Service	Liquid, gas, and vapor applications
Protocols	4–20 mA HART (Output Code A)
	Output
	Two-wire 4–20 mA, user-selectable for linear or square root output. Digital
	process variable superimposed on 4–20 mA signal, available to any host
	that conforms to the HART protocol.
	Power Supply
	External power supply required. Standard transmitter operates on 10.5 to
	42.4 V dc with no load.
	Turn-On Time
	Performance within specifications less than 2.0 sections after power is
	applied to the transmitter.
