4. I/O Expansion Modules
• I/O expansion modules expand the
measurement and control capability of the
system
• Can be added to any 5200A, 5400, 5500D
network and physically positioned where
needed
• Analog Inputs (4-20 mA, 0-1VDC, 0-5 VDC
and digital (on/off)) for additional sensors
and 3rd party sensors with isolated 24 VDC
power for 4-20 mA sensors
• 4-20 mA Outputs to control valves, pumps,
etc. or to interface to a PLC
• Instrument power via 110 VAC/220 VAC
and 12 VDC

5. REM Expansion Module
• REM expansion modules expand the
control capability of the system with 4
additional dry contact relay’s
• Can be added to any 5200A, 5400,
5500D network and physically positioned
where needed
• Each dry contact relay can be powered
via 110 VAC/220 VAC or 12 VDC/24 VDC
power with a common, normally open
and normally closed connection to meet
most required control needs
• Instrument power via 110 VAC/220 VAC
and 12 VDC

6. Monitoring & Control

7. Monitoring & Control
YSI aquaculture instruments
offer a variety of ways to
automate your process:
- 4-20 mA output: scalable,
analog, versatile
- Dry-contact relays:
automated electrical
switching, ideal for on-site
alarms

8. Monitoring & Control
Analog output (4-20 mA)
- Using a controller instrument and
an IOEM, you can output a
proportional analog signal to a
pump directly, or to a series of
VFDs (variable frequency drives)
- With multiple VFDs, you have
backup pumps in case you
experience an equipment failure
YSI IOEM

9. Monitoring & Control
The 5500D continuously
monitors DO concentration in
the raceway.
YSI IOEM

10. Monitoring & Control
The IOEM module translates
the output value for the DO to
an analog signal.
YSI IOEM

11. Monitoring & Control
The VFDs interpret this analog
signal and scale their output
frequency as programmed.
YSI IOEM

12. Monitoring & Control
The pumps run at variable
speeds depending on the signal
that they receive from their
corresponding VFDs.
YSI IOEM

13. Monitoring & Control
This same system also outputs
a power consumption value
that is continuously monitored
and logged by the 5500D to
notify staff of pump failures or
excessive energy use.
YSI IOEM

14. Monitoring & Control
Dry-contact relays
- 5500D has 8 built-in dry-contact
relays (5200A has 4)
- Act as an automatic switch to
turn devices on and off
- Can be used to trigger alarms to
alert your staff of events that may
need their attention
- Can be connected to an
autodialer for backup alerts

15. Monitoring & Control
The 5500D continuously monitors
DO concentration in the tank.

16. Monitoring & Control
When a control condition is met, a
relay is triggered in the 5500D
(or an REM module if present)

17. Monitoring & Control
The relay, depending on how it is
connected, can activate or
deactivate pumps, alarms, feeders,
etc.

18. Monitoring & Control
The connected device will remain
active and the 5500D will continue
to monitor.

19. Monitoring & Control
Once the DO is back in its user-
specified range, the relay will
switch again, deactivating the
pump.

20. Monitoring & Control
Choose your optimum
dissolved oxygen value

21. Monitoring & Control
This value determines
when a “Low DO”
condition is triggered

22. Monitoring & Control
This value determines
when a “High DO”
condition is triggered

23. Monitoring & Control
These values determine a
secondary High or Low
condition, for applications
that demand a rapid
response

24. Monitoring & Control
Determine when the High
and Low alarms are
triggered here

25. Monitoring & Control
Choose which relays to
activate in the drop-down
boxes for each condition

26. Monitoring & Control
Other applications…
• pH control – pH sensors, dosing pumps, and relays
• Disinfection – ORP sensors, ozone or UV system, and relays
• Auto-top off – digital float switches, pumps, and relays
• Feed Smart™ system – built-in software, DO sensors, temperature
sensors, and relays
Solenoid dosing pump UV disinfection system Feeding systems

27. Feed Smart™ Feed Timer
• Standard in YSI 5200A, 5400 and 5500D
continuous monitors
• 5200A controls one feed system while the 5400
and 5500D can control up to 4 separate feed
systems
• Setup from monitor menu or from
AquaManager™ desktop software
• Can be used with most powered feeders
• Up to 255 feedings per day

28. • Can decrease feed amounts by user defined % based on
DO, Temperature and pH values (pH is for 5200A only)
• Increases feed amount on a daily basis using the user
defined FCR (Feed Conversion Ratio)
• Feed amounts are determined by “rate based” calculations
and a simple one-step calibration process
• Units of measure; ounce (oz.), pound (lbs.), kilogram (kg),
gram (g)
• Can be used with the REM module
Feed Smart™ Feed Timer

29. • Continuous Mode
- takes the number of feedings per day and divides them equally within 24 hour for each
day that you select to feed starting at midnight, i.e. feed 12 times per day will feed every
two hours
• Timed Mode
- input a start and end time, the software then takes the total number of hours to feed and
divides that by the number of feedings per day, i.e. start at 8:00am and end at 8:00pm
and the fed 12 times a day then the feeders will turn on once an hour between 8:00am
and 8:00pm

41. Best Location for Sensors
Sensor placement considerations:
- Location of aeration equipment
- Location of heating elements
- Location of feeders
- Flow of water/mixing
- Minimum water depth
Make sure that your sensor cap stays wet. If it
dries out, the paint layer can become brittle
and delaminated.
