12.2.5 “3-wire Current” Amplifiers 
Use the following wiring diagram when connecting an amplified transducer or in-line amplifier with a 3-wire current 
amplifier to a High-Level Input channel.  Examples of such devices include: 
•  transducers with the Option 2j internal amplifier (with shunt cal) 
•  Model U3W Universal In-Line amplifiers (with shunt cal) 
The High-Level Input channel’s Configuration Jumpers must be set as follow for proper operation. See “Excitation 
and Signal Jumpers”. 
•  (+)Excitation supply: “+28 VDC” 
•  (-)Excitation supply: “GND” 
•  Signal type: “voltage” 
•  Signal reference: “single-ended”

12.2.6 “2-wire Current” Amplifiers with Buffered 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 amplifier (not equipped with shunt cal) 
•  transducers with the Option 2k, 3d internal amplifier (buffered shunt cal) 
•  Model U2W Universal In-Line amplifiers (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” in section 12.3.
