12.2.7 “2-wire Current”

Amplifiers with Single-

wire Shunt Cal

Use the following wiring diagram when connecting an amplified transducer or in-line

amplifier with a 2-wire current amplifier to a High-Level Input channel. Examples of

such devices include

• transducers with the Option 2p internal amplifier (not equipped with shunt cal)

• transducers with the Option 2p,3d internal amplifier (single-wire shunt cal)

• transducers with the Option 2y internal amplifier (not equipped with shunt cal)

• transducers with the Option 2y,3d internal amplifier (single-wire shunt cal)

The High-Level Input channel’s Configuration Jumpers must be set as follows for

proper operation. See “Excitation and Signal Jumpers” on page 106.

• (+)Excitation supply: “+28 VDC”

• (-)Excitation supply: “GND”

• Signal type: “current”

• Signal reference: “single ended”
