Multiplexing Sensor Hub
Multiplexing Sensor Hub
The Multiplexing Sensor Hub (MSH) allows station owners to add additional sensors to existing sites without having to break concrete to run new conduit and wires.

DO MORE WITH EXISTING WIRING
The MSH utilizes a single, existing 4-wire probe or sensor cable to power and connect up to six total devices to an EVO™ 600 or EVO™ 6000 Automatic Tank Gauge (ATG).
The Multiplexing Sensor Hub increases ATG sensor inputs without having to run additional conduit.
General
- Inputs: (1) LL3 probe, (4) UDP devices, (1) switch/temperature sensor, (1) RS-485 sensor
- Output to EVO™ 600/6000 ATG: (1) RS-485
Input Capabilities
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.
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.
Compatibility
The FMP-MSH is capable of supporting the following devices:
Channel 1: FMP-LL3
Channel 2: FMP-DDS-U, FMP-DTS-U, FMP-EIS-U, FMP-DIS-U, FMP-HIS-U, FMP-CDS-U, FMP-LL3-29*
Channel 3: FMP-DDS-U, FMP-DTS-U, FMP-EIS-U, FMP-DIS-U, FMP-HIS-U, FMP-CDS-U, FMP-LL3-29*
Channel 4: FMP-DDS-U, FMP-DTS-U, FMP-EIS-U, FMP-DIS-U, FMP-HIS-U, FMP-CDS-U, FMP-LL3-29*
Channel 5: FMP-DDS-U, FMP-DTS-U, FMP-EIS-U, FMP-DIS-U, FMP-HIS-U, FMP-CDS-U, FMP-LL3-29*, FMP-ULS
Channel 6: FMP-ULS, FMP-UHS, FMP-HFS2, 10K Temperature Sensor
*The FMP-LL3-29 is integrated into the Corrosion Control™ water separator to detect water level in the vessel.
