CORROSION CONTROL
MULTIPLEXING
SENSOR HUB™
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 Series console.
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
Inputs
(1) LL3 probe, (4) UDP devices,
(1) switch/temperature sensor
Output to
EVO™ 600/6000: (1) RS-485
Approvals /
Certifications
UL Listed, ATEX / IECEx
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.
• 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.
