Emerson TREXCHPNA9S1S AMS Trex Device Communicator

Core Processing and Memory

• An 800 MHz ARM Cortex A8/NXP microprocessor powers all operations. This processor ensures fast menu response and quick device polling.
• 512 MB DDR3 SDRAM provides smooth multitasking capabilities. Users can run diagnostic applications without performance degradation.
• Internal storage includes 2 GB NAND flash plus 32 GB extended flash memory. This space holds thousands of device configurations and screen captures.
• Brand: Emerson delivers reliable communication tools trusted by automation professionals globally.
• Model: TREXCHPNA9S1S represents the AMS Trex Device Communicator with HART app, no wireless, and one-year support.

Display and User Interface

• The device features a 5.7 inch (14.5 cm) color VGA resistive touchscreen. This display size provides ample viewing area for device menus and process data.
• 640 x 480 pixel resolution delivers sharp text and clear graphics. Technicians can read information easily in various lighting conditions.
• Resistive touch technology allows gloved hand operation in the field. This proves essential for cold weather or chemical handling environments.

Communication and Application Specifications

• The Device Communicator communication module (C) enables reliable HART connections. It supports all standard HART commands and device descriptions.
• HART Application (H) provides comprehensive device configuration capabilities. Users can perform trim adjustments, loop tests, and diagnostic checks.
• Radio option 9 means this unit has no wireless functionality. This simplifies security compliance in networks without wireless access.
• Rechargeable Li-Ion Power Module (P) delivers consistent power for field work. The battery supports full shifts without recharging.
• Product certifications carry NA (No Approval) for general industrial use. This suits facilities without intrinsic safety requirements.
• Standard Support (S1) covers technical assistance for one full year. Users receive updates and help for their AMS Trex Device Communicator.

Environmental Tolerance and Durability

• Operating temperature ranges from -20°C to 55°C for harsh conditions. The device functions reliably in extreme heat or freezing environments.
• IP54 rating protects against dust ingress and water spray from all directions. This suits outdoor installations and washdown areas.
• The unit weighs only 1.5 Kg for comfortable handheld use. Technicians can carry it throughout long shifts without fatigue.
• Electromagnetic immunity prevents interference from nearby electrical equipment. Signal integrity remains high even in noisy plant environments.
• Frequency response accurately captures HART protocol communication signals. The device resolves 1-2 mA/sec changes for precise diagnostics.
• Measurement resolution displays HART variables up to five decimal places. This matches the native resolution of connected smart transmitters.

Frequently Asked Questions

• Q: What is the advantage of 32 GB extended flash in the TREXCHPNA9S1S?
  A: Extended flash stores thousands of device configurations, screen captures, and future software updates. Users never run out of space for critical data.
• Q: Can I add wireless capability later to this model?
  A: Radio option 9 means no wireless hardware is installed. Adding wireless later is not possible; choose a W model for wireless needs.
• Q: How does the resistive touchscreen perform compared to capacitive screens?
  A: Resistive screens work with any stylus or gloved hand, essential for outdoor and cold weather use. They provide precise control in wet conditions.
• Q: What HART commands does this communicator support?
  A: It supports all universal, common-practice, and device-specific commands for HART devices. This includes configuration, trim, and diagnostics.
• Q: Is the device suitable for use in hazardous areas?
  A: NA certification means no intrinsic safety approvals. Use this model only in general purpose, non-hazardous locations.
• Q: What is the typical battery life during continuous HART communication?
  A: The Li-Ion module provides up to 8 hours of active use. Standby time extends much longer between charging cycles.
• Q: Does the 5.7 inch display show enough information for complex device menus?
  A: Yes, the 640 x 480 resolution displays full menus without scrolling. Users see multiple parameters simultaneously for efficient configuration.
