Quick Start Guide
The Rosemount 6888C accepts line voltage at 120/240 Vac ±10%,
50/60 Hz. No setup is required.
3. Connect the 4-20 mA signal wires at the transmitter. Use a shielded
twisted wire pair. Do not allow bare shield wires to contact the circuit
boards. Insulate the shield wires prior to termination.
The transmitter electronics are loop-powered (i.e., the 4-20 mA
signal wires supply 24 Vdc from the DCS or an external power
supply).
