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
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.
