The Emerson TREXCHPNAWS1 is a powerful HART communicator from the AMS Trex family. Technicians use this device to configure and troubleshoot HART instruments. Unlike other models, this version supports HART applications exclusively. It does not include Foundation Fieldbus capabilities. Additionally, this unit carries no hazardous area certifications. Therefore, it suits general purpose industrial environments only.
Emerson built the TREXCHPNAWS1 around a robust computing platform. Its 800 MHz ARM Cortex A8 processor ensures fast response times. Meanwhile, the Windows Embedded Compact 2013 operating system provides a familiar interface. For field use, the rechargeable Li-Ion power module lasts over eight hours. Wireless options include Bluetooth, WiFi, and NFC for easy connectivity.
The TREXCHPNAWS1 runs on the Base Trex Platform. Its communication module is type C for Device Communicator functions. The applications included are strictly HART only. For power, this model uses type P rechargeable Li-Ion module. Product certifications show NA, meaning no approval for hazardous areas. The radio options are W for wireless capability. Support comes as S1, which is standard support for one year.
Several memory components power this device. Internal flash memory includes 2GB NAND storage. Additionally, there is 32GB of extended flash memory. The system RAM measures 512 MB of DDR3 SDRAM. These specifications allow smooth operation even with multiple device files open.
The display measures 5.7 inches diagonally. It uses a color VGA resistive touchscreen. Screen resolution reaches 640 x 480 pixels. This display works well with gloves in industrial settings. The microprocessor is an 800 MHz ARM Cortex A8 from NXP. For operating system, the TREXCHPNAWS1 runs Windows Embedded Compact 2013. This OS provides reliable performance for field tools.
The TREXCHPNAWS1 includes several terminal options for flexibility. HART terminals use two banana plug connectors. Users can select internal resistance of 250 Ohm or 500 Ohm. For HART plus power terminals, additional features appear. These terminals communicate with HART devices and power one HART unit. They include a 167 Ohm resistor, current control, and an ammeter. Current range goes from 3 to 22.5 mA.
Furthermore, this communicator includes mA terminals for external ammeter use. These measure current on 4-20 mA loops. Two banana plugs handle up to 22.5 mA with 0.1 mA resolution. Foundation Fieldbus terminals are also present. They use two banana plugs for FF device communication. For FF plus power, a single banana plug connector appears. This includes a power conditioner and supports 0 to 38 mA.
Wireless features make the TREXCHPNAWS1 very convenient. Bluetooth 2.1 provides connectivity up to 10 meters. WiFi 802.11 b/g reaches up to 33 meters. Active NFC works within 20 centimeters. All these radios carry FCC, CE, RED, and IC certifications. However, wireless availability depends on local spectrum approvals.
For wired connections, a micro USB 2.0 connector is available. Always disconnect the USB cable before connecting to a field device. This prevents potential communication conflicts. A built-in rechargeable lithium-ion battery module powers everything. Normal operation lasts over eight hours on a full charge. Charging time takes approximately three to four hours.
1. Which protocols does the TREXCHPNAWS1 support?
This communicator supports HART applications only. It does not include Foundation Fieldbus capabilities. Choose another model if you need FF support.
2. Is this device safe for explosive environments?
No, it is not. The TREXCHPNAWS1 carries NA product certifications. This means no hazardous area approvals. Use it only in general purpose locations.
3. How long does the battery last on a full charge?
The rechargeable Li-Ion battery lasts over eight hours under normal use. Charging takes about three to four hours with the included AC adapter.
4. Can I power a HART device directly from this communicator?
Yes, you can. Use the HART plus power terminals for this purpose. These terminals provide power, a 167 Ohm resistor, and current control from 3 to 22.5 mA.
5. What operating system runs on this device?
The TREXCHPNAWS1 runs Windows Embedded Compact 2013. This operating system supports fast boot times and reliable field performance.
