Yokogawa -Â Model YS1500 -Indicating Controller for Single Loop
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.
- Excellent legibility thanks to a full-dot color LCD: High visibility of the display screen is ensured even in direct sunlight in the early morning and late afternoon. The user can freely access a desired operation display from meter, trend display, bar graph, alarm, and event displays. All parameters can be set via the front panel display.
- Function selection mode (needs no programming): The multi-function controller mode allows control to be selected from frequently used functions (single-loop, cascade, or selector control) without programming. Function assignments to digital and analog inputs/outputs (DIs, DOs, AIs, and AOs) can be determined by parameter settings.
- Fail-safe: Thanks to dual CPU (one for control and one for display), display and manual operations are enabled even during a failure of either CPU. The hard manual circuit incorporated independently from the digital circuits enables the controller output to be adjusted manually during a failure of a digital circuit including both CPUs. (The hard manual circuit is not incorporated when the /NHM option is specified.)
- Nonvolatile memory for memory backup: No battery or capacitor is used for memory backup, facilitating maintenance.
- AC/DC dual power supply with wide operating voltage range to ensure stability against supply voltage fluctuations: Can be driven by either an AC (100 V) or DC (24 V) power supply. Furthermore, the DC power supply enables receiving power without polarity. (Must be specified upon ordering if using a 220 V AC power supply.)
- 250 mm depth (for basic types only)
- Dust- and splash-proof IP54 faceplate (for basic type only)
- CE Mark (for basic type and YS100 compliant type only)
- FM Nonincendive explosion protection (optional for basic type only)
- Communication (optional)
- Ethernet (Modbus/TCP; for basic type only)
- RS485 (PC Link, Modbus and YS protocol; unavailable for YS80 internal unit-compatible type)
- DCS-LCS communication - Compatibility with YS100 Series: Setting and control operations can be done with the same feel. For basic-type cases, terminal-to-terminal pitches differ but the signal-to-terminal arrangement is almost the same.

Connection modes: USB, Ethernet or RS485
When connecting via RS485 or Ethernet, a communication option is required on the main unit.
Full set of computation functions

Supports parameter setting for all YS1000 models
Password protection function
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.
Designed with a Lightweight, Compact Case
Provides for greater freedom of instrumentation design
Compact, lightweight design allows the use of smaller and less expensive panel. Moreover, it allows attachment to doors which was previously difficult.
Control Output Backup Function
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.
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
Battery free memory backup
Nonvolatile memory is used for memory backup. Service life is improved because no batteries, backup capacitors, or other components are used.
AC/DC power supply resists powerline fluctuations
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).
Improved basic control performance
The YS1000 series achieves higher performance than previous models (YS100 series).
- I/O accuracy
- Voltage input accuracy: ±0.2% ⇒ ±0.1%
- Voltage output accuracy: ±0.3% ⇒ ±0.1%
- Current output accuracy: ±1.0% ⇒ ±0.2%
- Internal data resolution of the I/O signal: 1/1000 ⇒ 1/10000
- Internal computation resolution of PID and other computations: 1/4096 ⇒ 1/65536
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.
Other specification
- CE Mark (for basic type and compatible type for YS100)
- FM nonincendive approved (FM Class I, DIV 2)
- CSA safety and nonincendive approved (Class I, DIV 2)
Ethernet support
- 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
Self-tuning (STC)
Simplifies tuning when starting up or changing the process unit under control.
The YS1700/YS1500’s six DI/DO terminals can be used for both input and output.
