The TREXCHPKLWP1S from Emerson helps you configure and test HART devices in the field. This portable unit combines a rugged design with advanced communication features. You can use it for troubleshooting, calibration, and device setup. Many technicians trust the AMS Trex platform for daily maintenance tasks.
The TREXCHPKLWP1S runs on an 800 MHz ARM Cortex A8/NXP processor. It has 512 MB DDR3 SDRAM for smooth operation. Internal storage includes 2 GB NAND and 32 GB extended flash. This gives you plenty of space for device data and updates.
Additionally, the display measures 5.7 inches (14.5 cm). It uses a color VGA resistive touchscreen. Gloves or a stylus work well with this screen. The battery delivers over 8 hours of typical use. Moreover, the rechargeable Li-Ion power module reduces downtime.
For connectivity, this model includes Bluetooth, WiFi, and NFC radios. However, wireless availability depends on local spectrum approvals. The communication module supports the HART application. You also get a TREXCHPKLWP1S lead set with connectors included.
This device communicator withstands tough conditions. First, the operating temperature ranges from -20 to 55°C (-4 to 122°F). Second, the enclosure rating is IP54. This protects against dust and water splashes. Third, it survives a 1-meter drop onto concrete. Shock testing confirms this durability.
Furthermore, the unit weighs approximately 2.9 lbs (1330 grams). Its compact size makes it easy to carry. The included hand strap adds extra security during use. Therefore, you can work in refineries, power plants, or chemical facilities without worry.
The TREXCHPKLWP1S carries KL certification. This includes ATEX, CSA (US/Canada), and IECEx Intrinsically Safe. FISCO applies where relevant. These approvals allow safe use in hazardous areas. Many industries require such certifications for field tools.
Besides that, the premium support (P1) covers one year. This includes protection against accidental damage. Standard warranty against manufacturing defects also applies for 12 months. Emerson provides this coverage directly.
Setting up the TREXCHPKLWP1S is straightforward. First, charge the rechargeable Li-Ion power module using the AC adapter. Next, attach the hand strap to the unit. Then connect the lead set with connectors to your HART device.
Meanwhile, turn on the communicator and navigate the menu. The resource DVD contains software and guides. You can also activate the ValveLink Mobile application at no charge. Activation requires an internet connection after powering on the Trex unit.
Finally, use the USB cable to transfer data to a PC. The quick start guide explains basic operations. Many users complete setup within 10 minutes.

1. Can the TREXCHPKLWP1S communicate with non-HART devices?
No, this model supports only HART application. For other protocols, choose a different communication module.
2. Is the wireless function available in all countries?
No, Bluetooth, WiFi, and NFC work only where spectrum approvals are obtained. Check local regulations before ordering.
3. How long does the rechargeable battery last per charge?
It provides 8+ hours of typical use. Heavy usage may reduce this time slightly.
4. Does the carrying case protect against heavy rain?
The case adds convenience but the unit itself has IP54 rating. It resists splashes, not submersion.
5. Can I upgrade storage on the TREXCHPKLWP1S?
No, internal flash is fixed at 32 GB extended and 2 GB NAND. Use the USB port for data transfer instead.
