12.2.8 Low Voltage dc-dc LVDTs
Use the following wiring diagram when connecting a low-voltage
dc-dc LVDT to a High-Level Input channel. Examples of such
devices include
• ModelsDLB,DLEandDLFdc-dcLVDTs
The High-Level Input channel’s Configuration Jumpers must be
set as follows for proper operation. See “Excitation and Signal
Jumpers” on page 56.
• (+)Excitationsupply:“+12Vdc”
• (-)Excitationsupply:“GND”
• Signaltype:“voltage”
• Signalreference:“singleended”
