Yokogawa PS65*A Programmable controller

Product Detailed Description

• Functionality:

• Measurement and Display: Accurately measure process variables from various sensors (thermocouples, RTDs, mV, V, mA inputs) and display them clearly on an integrated LCD.

• Control Modes: Implement a variety of control algorithms including PID control, ON/OFF control (with hysteresis), two-position two-level control, heating/cooling control, and position proportional control for actuators. Many models support single-loop, dual-loop, and cascade control.

• Alarm Functions: Offer multiple alarm types such as measured value (PV) high/low limit alarms, deviation alarms, rate-of-change alarms, setpoint alarms, and output alarms (e.g., heater burnout alarm with optional /HA).

• Computation Functions: Include signal computation features like bias, filter, PV tracking, square root extraction, and multi-segment linearizers.

• Ladder Sequence Control: Many models incorporate a built-in ladder sequence function, allowing for simple logic control similar to PLCs, reducing the need for external devices and wiring.

• Communication: Support various communication protocols for integration into larger control systems (e.g., Modbus RTU, Modbus TCP/IP (Ethernet), PROFIBUS-DP, CC-Link, DeviceNet).

• Recipe Management: Enable the storage and execution of different control recipes.

• Features:

• Easy-to-read Displays: Utilize 14-segment color LCDs (e.g., active color PV display) with large characters and intuitive navigation guides and keys for enhanced usability and clear status indication.

• Universal Inputs/Outputs: Standard universal I/O flexibility supports a wide range of sensor types and controlled devices.

• Compact Design: Short depth (e.g., 65mm for some models) helps save instrument panel space.

• Robust Construction: Designed for industrial environments with dust and waterproof front panels (e.g., IP66/NEMA 4 compliant).

• Auto-tuning: Simplifies PID parameter tuning for optimal control performance.

• Software Support: Often supported by PC-based parameter setting software (e.g., LL50A) for easier configuration and data management.

• Security: Password protection to prevent unauthorized parameter changes.

• Cost-Effective: Built-in ladder sequence function and universal I/O often eliminate the need for peripheral devices and associated wiring, reducing overall system cost.

• Flexibility and Versatility: Wide range of input/output types, control modes, and communication options make them adaptable to diverse applications and integration into various control systems.

• Space-Saving: Compact dimensions allow for efficient panel mounting.

• Robust and Reliable: Designed for harsh industrial environments, ensuring long-term stable operation.

• Simplified Engineering: PC-based software tools and clear documentation streamline parameter setting and data management.

Precautions

• Installation:

• Mount in a well-ventilated location to prevent internal temperature rise.

• Avoid locations with strong mechanical vibration, direct sunlight, or close to heaters.

• Ensure terminals are not inadvertently touched and that the instrument is horizontally leveled.

• Install in locations with stable temperatures (ideally around 23°C).

• Avoid locations with substantial amounts of oily fumes, steam, moisture, dust, or corrosive gases.

• Do not mount directly on flammable surfaces.

• Electrical Safety:

• Do not operate in explosive atmospheres or near strong electromagnetic field-generating sources.

• Only Yokogawa service personnel should remove internal units or replace fuses due to high voltage parts.

• Observe all safety precautions described in the user's manual (e.g., warnings for electric shock).

• Wiring:

• Ensure proper wiring and grounding according to the provided manuals.

• Parameter Setting:

• Carefully refer to parameter maps and lists in the manual, as some parameters may not be displayed depending on the model and suffix codes.

• Utilize password protection to prevent unintentional parameter changes.

• Maintenance:

• Regularly check the instrument for any signs of damage or malfunction.

• Refer to the user's manual for recommended maintenance procedures.
