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.
Using ROCLINK 800, you can configure the I/O on the CPU module's
optional I/O assembly to set the loop output power to 10 volts dc or 24
volts dc. The I/O module only supports 24 Volts dc loop output power.
Note: The CPU I/O assembly uses the CPU's loop power output and
ground connections.
The intent of the loop output power is 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 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.
The input/output (I/O) options for the FB107 provide terminals for
expanded monitoring and control applications. I/O can be used 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 are configurable 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).
You can add an expansion rack to the FB107 base unit to increase I/O
by four slots for a total of six slots of I/O. The FB107 supports up to six
