Yokogawa YS1500 Indicating Controller YS1500 Indicating Controller

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.Yokogawa YS1500 Indicating Controller Standard models are smaller and lighter than earlier series,Yokogawa YS1500 Indicating Controller
requiring less space for installation, and are compliant with international safety standards including the CE Mark and FM,
CSA nonincendive (optional) approvals. For easy replacement of earlier controllers, Yokogawa YS1500 Indicating Controller

models requiring the same panel Yokogawa YS1500 Indicating Controller
cutout dimensions and depth as those of earlier models are also offered.

Excellent legibility thanks to a full-dot, TFT 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 Yokogawa YS1500 Indicating Controller
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,Yokogawa YS1500 Indicating Controller
and AOs) can be determined by parameter settings.Yokogawa YS1500 Indicating Controller
• 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 Yokogawa YS1500 Indicating Controller
incorporated when the suffix code -2xx option is specified.)

• Nonvolatile memory for memory backup: No battery or capacitor
is used for memory backup, facilitating maintenance.Yokogawa YS1500 Indicating Controller
• 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.)Yokogawa YS1500 Indicating Controller
• 250 mm depth (for basic types only)Yokogawa YS1500 Indicating Controller
• Dust- and splash-proof IP54 faceplate (for basic type only)
• CE Mark (for basic type and YS100 compliant type only)Yokogawa YS1500 Indicating Controller 
• FM Nonincendive explosion protection (optional for basic
type only)

• CSA Nonincendive explosion protection (optional for basic
type) (However, certification is planned for the YS100-compatible
type (with YS100 case)).Yokogawa YS1500 Indicating Controller
• Communication (optional)Yokogawa YS1500 Indicating Controller
- Ethernet (Modbus/TCP; for basic type only)
- RS485 (PC Link, Modbus and YS protocol; unavailable for YS80
internal unit-compatible type)Yokogawa YS1500 Indicating Controller
- 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.
