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.
