12.2.6 “2-wire Current” Ampliers with Buff-
ered 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2kinternalamplier(not
equipped with shunt cal)
• transducerswiththeOption2k,3dinternalamplier(buffered
shunt cal)
• ModelU2WUniversalIn-Lineampliers(notequippedwith
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 56.
• (+)Excitationsupply:“+28Vdc”
• (-)Excitationsupply:“GND”
• Signaltype:“current”
• Signalreference:“singleended”
