Emerson FloBoss 107 User Manual

FloBoss 107 Instruction Manual
4-10 Inputs and Outputs Revised June-2017
The I/O module only supports 24 volts dc loop output power. The CPU
module’s I/O assembly uses the CPU’s loop power output and ground
connections.
The intent of the loop output power is to power devices (such as
Rosemount transmitters) that require 24 volts dc to ground and then send
the FB107 a 4 to 20 mA signal based on pressure, temperature, level and
such.
The 10-volt loop output power is intended for low power transmitters that
send a 1 to 5 volts dc rather than a 4 to 20 mA signal.
The loop current is designed to deliver 80 mA to power two field devices
that connect back to the two analog inputs.
