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”
