Yokogawa BT200-P00 BRAIN Terminal Module 4351B

Engineered for precision diagnostics and configuration in industrial environments, the Yokogawa BT200-P00 serves as a portable interface for BRAIN protocol-compatible field devices. This terminal streamlines maintenance workflows across process control systems where real-time adjustments and troubleshooting matter most.

Field technicians routinely deploy this module in chemical plants and oil refineries for on-site calibration of DPharp pressure transmitters or ADMAG flow meters. Its rugged housing survives vibrations near centrifugal pumps while maintaining communication integrity. For instance, a maintenance engineer recently used it to recalibrate a YEWFLO vortex flowmeter during a 48-hour plant turnaround, completing setup in under 15 minutes thanks to the intuitive menu navigation.

Technical Advantages

• Automatic power-off preserves battery life during intermittent use
• Integrated printer for instant configuration documentation
• BRAIN protocol compatibility ensures seamless integration with legacy Yokogawa systems
• Redundant memory storage maintains settings during battery replacement
• Low-voltage alarm prevents data loss during critical operations

The terminal’s intrinsically safe design meets Zone 1 hazardous location requirements, making it suitable for natural gas processing facilities where explosive atmospheres exist. Users appreciate the tactile feedback from its mechanical keypad during gloved operation, though some note the LCD contrast diminishes slightly below 40°F (-20°C). When paired with YT200 series transmitters, the two-way communication enables real-time sensor diagnostics that identify process anomalies before they trigger shutdowns.
