The YS1500 Indicating Controller incorporates fundamental control functions required for PID control. Necessary functions can be selected in accordance with the user's purpose. The available functions include those functions necessary for input signal processing, such as square root extraction and linear segment conversion, and feed-forward calculation. Single-loop, cascade and selector mode is also available. Standard models are smaller and lighter than earlier series, requiring less space for installation, and are compliant with international safety standards including the CE Mark and FM nonincendive (optional) approvals. For easy replacement of earlier controllers, models requiring the same panel cutout dimensions and depth as those of earlier models are also offered.
Connection modes: USB, Ethernet or RS485
When connecting via RS485 or Ethernet, a communication option is required on the main unit.
Supports parameter setting for all YS1000 models
Passwords can be assigned to user programs to prevent unauthorized access to proprietary programs.
A password on the main unit prevents unexpected changes in the engineering parameters.
Compact, lightweight design allows the use of smaller and less expensive panel. Moreover, it allows attachment to doors which was previously difficult.
The control output backup function comes standard with YS1000 series controllers (YS1700 and YS1500) and the Manual Station for MV Setting (YS1360).
With dual-CPU construction (main CPU and display CPU), manual control capability and display continues even if an abnormality occurs on one of the CPUs. If controller self-diagnostics detects a control circuit failure, the controller can suspend analog/digital output, switch to manual mode and allow manual control by operator.
|Main CPU fail||Display CPU fail||All CPU and
|Control with "Hard manual"||X||X||X|
|Manual operation with front keys||X||X||N/A|
|Display for PV and SV||X||X||N/A|
Independent manual override is built into the control circuits, ensuring that control output can continue even when a control circuit including the CPU experiences a problem.
*Comes standard with YS1700-1xx, YS1500-1xx, YS1360-1xx
Nonvolatile memory is used for memory backup. Service life is improved because no batteries, backup capacitors, or other components are used.
The AC/DC (100 V /24 V ) power supply powers the instrument to provide consistent performance.Also accepts DC power regardless of polarity (specify 220 V power supply when ordering).
The YS1000 series achieves higher performance than previous models (YS100 series).
Use the YS110 portable manual station when exchanging or performing maintenance on a controller. You can switch to the spare controller without interrupting the control output.
Tougher environmental resistance.
The instrument can be easily connected to DAQWORX, SMARTDAC+, general-purpose SCADA, and OPC servers via Ethernet (Modbus/TCP).
Ethernet : Available to the YS1000 basic type. Modbus/TCP server function (one connection).
Connections are enabled using the FA-M3' s UT link module and the RS485 communication function. No programming is necessary to exchange data between the instrument and the FA-M3.
The YS1000 can also be connected to PLCs of various manufacturers via the Modbus communication protocol.
As with previous models, communication with Yokogawa's DCS (CENTUM) is supported. This is ideal for DCS backup in chemical plants and other applications requiring extreamly high reliability.
Applicable Models: YS1700,YS1500,YS1350,and YS1360
Simplifies tuning when starting up or changing the process unit under control.
Setpoint filter (SVF)
Can optimize tracking with changes in set-points. Also can maintain optimum responsiveness to disturbances.
The YS1700/YS1500’s six DI/DO terminals can be used for both input and output.
To technology in iron & steel industry is continuously improved to obtain the best possible performance. The improved plant performance gives rise to the higher quality improvement and lower cost, and simultaneously environmental friendly plant operation.
Continuous technology improvement is ongoing in the pulp & paper industry to obtain the best possible performance. The improved plant performance translates to the higher quality improvement and lower cost, and simultaneously environmental friendly plant operation.
In district heating/cooling and other systems, signals from flow meters can undergo temperature compensation in a totalizer to measure usage of warm water and other quantities. Here we give an example of how to perform temperature compensation of flow using the YS1700 Single Loop Controller in place of a dedicated totalizer.
Automated control of industrial boilers is an excellent application for YS1700 microprocessor-based loop controllers. These instruments can be programmed to perform the operations of plant master, boiler master, fuel and air control with oxygen trim and drum level/feedwater control.
