YS170 can control TWO independent loops
Where cost effectiveness is a key issue
Three pre-configured control strategies + custom programming
YS150 does not require any custom programming
All configuration is performed at the front panel display
SINGLE, CASCADE & AUTO-SELECTOR control modes
YS110 - bypass station used in the event of controller outage
Any installation with critical control loops should have ONE standby station
YSS20 software is required to write a custom YS170 program
YS131 trends two inputs and has eight alarm functions
Looks & feels just like the controllers
YS135 can provide a set point to an external control device
Local set point adjustment bypassing a master device
YS136 permits MANUAL output adjustment
Used with a DCS or PLC installation

3. YS100 Hardware Platform Surface mount technology: reliable & low power
Non-volatile memory (EEPROM)
Up to 400 lines of programming (YS170)
Modular construction with separate boards for:
Power supply (auto sensing AC or DC voltage)
Communications (RS485, DCS, Peer-to-Peer)
Signal conditioning input
Independent CPU’s for control and display
24VDC Power for two-wire transmitters
Integral HARD MANUAL backup
Surface mount allows a smaller FOOT PRINT
Only 12.6 inches in length allows installation into smaller control panels
Modular construction allows communication cards & signal conditioning cards to be easily field retrofitted
The control output can be manipulated & observed on the front display if the main CPU fails
Non-isolated loop power for two transmitters is available (60mADC maximum)
Integral HARD MANUAL allows continuous operation even if the controller fails

4. YS150 Pre-Configured No programming Setup without PC
3 ready to go strategies
