The YS1350 is a manual setter that allows for manually outputting setting signals to controllers and the like. The YS1360 is a manual setter that allows for manually outputting operation signals to operation terminals. The YS1350 and YS1360 include as standard an operation mode selector switch [cascade (C) and manual (M)], status input-based operation mode selector function, and operation mode discrimination status output function. The YS1350 and YS1360 offer high reliability thanks to Yokogawa's proprietary technology, user friendliness, and expandability. The basic type conforming to the DIN short case size contributes to space saving for mounting, and complies with standards (CE and FM). For easy replacement of earlier models requiring the same panel cutout dimensions and depth as those of earlier models are also offered.



  • A full-dot, semi-reflective color LCD Clear 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 screen from meter, trend, bar graph, alarm, and event displays. All parameters can be set via the front panel display.
  • The parameters can all be set by operation on the front panel (no need to draw out the internal unit).
  • Parameters can also be set using YSS1000 Setting Software available separately.
  • Can be driven by either an AC (100 V) or DC (24 V) power supply. (Must be specified upon ordering if using a 220–240 V DC power supply.)
  • Dust- and splash-proof IP54 compatible faceplate (for basic type only)
  • Depth 250 mm (only for the basic type)
  • No battery or capacitor is used for memory backup. No maintenance is required because batteries and backup capacitors are not used.
  • CE mark (for basic types and YS100-compatible type only)
  • FM non-incentive explosion protection (optional for basic types only) (Under an application)
  • Communication (option)
    Ethernet (Modbus/TCP) (for basic types only)
    RS485 (PC Link, Modbus, YS protocol, unavailable for YS80 internal unit-compatible type)
  • Compatibility with the YS100 series Setting and control operations can be done with the same feel. In the case of the basic type, terminal-to-terminal pitches differ but the signal-to-terminal arrangement is almost the same. The following functions are included to ensure compatibility with the SMST.
    ▪ Meter Display was added to the Operation Display.
    ▪ Housing for replacement purposes (SHUP-000 separately available)

Three connection modes

Three connection modes
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.

High reliability

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).

Dual CPU

Dual CPU

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.

Manual operation-"hard manual"

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

Manual operation-"hard manual"


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


Controller online replacement function (portable manual station)

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.

Please check the following 3 points. Is an input signal going to the cascade input terminal? If the cascade input terminal is open (IOP), the instrument is designed not to change from AUTO to CAS. Is CMOD1=CAS or CMP set? Is the operation mode A...
When using a 24 VDC power supply, since the rated power specification is 3 W, use the YS021 (250 Ω shunt resistor). For others, you can use the X010-250-1 external precision resistor with a rated power of 0.5 W.
If you share (wire) the DI's COM there will be no isolation between the DI's inputs, but otherwise there should be no problem.
