General Specifications l tiona Func ment nce Enha n GENERAL 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, CSA 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. • 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) • CSA Nonincendive explosion protection (optional for basic type). • 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. • 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 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 suffix code -2xx 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.)
