FloBoss 107 Instruction Manual
1-10 General Information Revised June-2017
1.3.8 Built-in Resistance Thermal Device (RTD)
The FB107 supports a direct input from a resistance thermal device (RTD)
sensor to measure flowing temperature. An RTD temperature probe
typically mounts in a thermowell on the meter run. The RTD has a
measurement range of

40 to 400°C (

40 to 752°F). The RTD is located
on the CPU.
1.3.9 Built-in Loop Output Power
Using ROCLINK 800, you can configure the I/O on the CPU module to
set the loop output power to 10 volts dc or 24 volts dc:

The 24-volt setting of the loop output power is used to power
devices that require 24 volts dc to ground, allowing the external
device to send the FB107 a 4 to 20 mA signal based on pressure,
temperature, level, and such.

The 10-volt setting of the loop output power is intended for low
power transmitters. The loop current is designed to deliver 80 mA
to power two field devices that connect back to the two analog
inputs.
Note: The CPU I/O assembly uses the CPU’s loop power output and
ground connections.
The I/O module only supports 24 volts dc loop output power. When 10
volts is selected, the loop output power will be 10V+ depending on input
power supply
1.3.10 Optional Inputs and Outputs
The input/output (I/O) options for the FB107 provide terminals for
expanded monitoring and control applications. Use I/O to drive a sampler
or odorizer, open a valve, or monitor an additional analog input.
You can order the expanded 6-point I/O as an:

I/O assembly that mounts directly on the CPU module (optional I/O
assembly).

I/O modules that mount in the I/O slots.
Both configurations provide terminations for six points of I/O and both
provide the same selections for I/O. You can configure five of the six
points of I/O using ROCLINK 800 software.
The six points of I/O consists of:

Two analog inputs (AI) or discrete inputs (DI).

One analog output (AO) or discrete output (DO).

One discrete output (DO).

Two pulse inputs (PI) or discrete inputs (DI).
