MULTIPLEXING
SENSOR HUB™
CORROSION CONTROL
The Multiplexing Sensor Hub™ (MSH) allows you to use a
single 4-wire cable to connect up to six devices to an
EVO™ 600 or EVO™ 6000 automatic tank gauge (ATG).
HIGHLIGHTS
• For retrofit applications: the MSH can use existing 4-wire
probe and sensor cables to add additional probes or
sensors, providing expanded monitoring capabilities
without the need to break concrete to run additional cable.
• For new applications: the MSH delivers labor and materials
savings by reducing the amount of conduit and cable
required for monitoring devices within a containment sump.
• Ideal for use in adding a Corrosion Control™ Water
Separator and corrosion detection sensors (FMP-CDS-U)
to an existing tank sump and provides all necessary input
capabilities for this system.
SPECIFICATIONS
• Six input channels provide a wide assortment of device
communication capabilities:
• Channel 1: Always on, for FMP-LL3 digital inventory
and leak detection probes.
• Channel 2-5: Multiplexed, for 2-wire universal device
protocol (UDP) communication devices.
• Channel 5: Additional capability for 2-wire devices.
• Channel 6: For any dry-contact single pole single throw
(SPST) switch, a flow switch, two-wire device, or
temperature sensor based on a 10k thermistor.
Input Capabilities
The FMP-MSH is capable of supporting the following devices:
General
• Inputs: (1) LL3 probe, (4) UDP devices, (1) switch/
temperature sensor
• Output to EVO™ 600/6000 ATG: (1) RS-485
Theory of Operation
The FMP-MSH requires a minimum of four wires connected
directly to an EVO™ 600 with an RS485 module. The four
connections are power, ground, and A and B communication
for the RS485 module. If a sump has two input field cables
that are both 2-conductor cables, the A and B connections
should be wired in the same cable that must be a twisted
pair. Power and ground should be on the other cable. If it is a
new installation, Belden™ cable #7962A, or a cable with
equivalent parameters, is recommended. The FMP-MSH can
power and accept input from 6 different probes or sensors.
