YOKOGAWA PK200-A13

YOKOGAWA PK200-A13

Overview:

The YOKOGAWA PK200-A13 is a high-performance current-to-pneumatic (I/P) converter designed by Yokogawa Electric to bridge electronic control systems and pneumatic actuators in process industries. It accurately converts standard 4–20mA DC analog signals into proportional pneumatic pressure outputs, enabling precise control of valves, dampers, and other pneumatic devices. Built for reliability and efficiency, the PK200-A13 is a trusted component in oil & gas, chemical, power, and water treatment applications.

Model Code Explanation: YOKOGAWA PK200-A13

Yokogawa’s PK200 series uses a structured suffix system for clear configuration identification:

• PK200: Base model – Current-to-Pneumatic (I/P) Converter
• A: Input signal = 4–20mA DC (standard electronic control signal)
• 1: Output signal = 20–100kPa (3–15psi) standard pneumatic range
• 3: Connection code – Air: Rc1/4 female; Electrical: G1/2 female

Full Meaning: YOKOGAWA PK200-A13 = I/P Converter, 4–20mA DC Input, 20–100kPa Output, Rc1/4 Air & G1/2 Electrical Connections.

Core Features & Benefits

1. Precision Conversion with Exceptional Stability

The PK200-A13 delivers ±0.1% repeatability and ±0.2% linearity, ensuring consistent, accurate signal translation between electronic and pneumatic systemsYokogawa Electric Corporation. Its electronic feedback design minimizes drift, maintaining performance over long-term operation and reducing calibration frequency.

2. Wide Operating Temperature & Rugged Construction

With an operating range of -40°C to +80°C, the unit withstands extreme industrial environments, from freezing outdoor installations to high-temperature process areas. The epoxy-coated aluminum housing and stainless steel gauges resist corrosion, dust, and moisture, extending service life.

3. Energy-Efficient Air Usage

Designed for sustainability, the PK200-A13 consumes only 4Nl/min of air at standard pressure, significantly reducing operational costs compared to older I/P converters. Its high output capacity (110Nl/min) supports large actuators without additional boosters.

4. User-Friendly Operation & Maintenance

Front-mounted zero/span adjustments and an auto/manual switch simplify on-site configuration and troubleshooting. Built-in stainless steel gauges allow instant pressure monitoring, eliminating the need for external test equipment. All adjustments are tool-free, reducing maintenance time.

5. Flexible Configuration & Compatibility

The standard 4–20mA input and 20–100kPa output match global industrial norms, ensuring compatibility with most DCS, PLC, and pneumatic actuator systems. Optional configurations (doubled output, intrinsically safe) adapt to specialized applications.

6. Compact, Space-Saving Design

With dimensions of 130×180×95mm, the PK200-A13 fits easily in control cabinets, field enclosures, or direct valve mounting setups. Its lightweight (3kg) construction simplifies installation and reduces structural load.
