12.2.7 “2-wire Current” Ampliers 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amplier(not
equipped with shunt cal)
• transducerswiththeOption2p,3dinternalamplier(single-
wire shunt cal)
• transducerswiththeOption2yinternalamplier(not
equipped with shunt cal)
• transducerswiththeOption2y,3dinternalamplier(single-

The High-Level Input channel’s Configuration Jumpers must be
set as follows for proper operation. See “Excitation and Signal
Jumpers” on page 56.
