Do More With A Single Tool, From A Single Provider.
The AMS Trex Device Communicator provides the tools field technicians need, in one ruggedized, intrinsically safe, easy to transport package.
Power the Loop technology eliminates the need to locate and carry a compatible power supply or loop simulator before connecting to a device. Technicians can perform configuration on devices before power and I/O infrastructure are in place.
Anticipates user needs, provides troubleshooting information, and allows for easy navigation through the menus and type criteria with a large touchscreen keyboard.
AMS Trex supports two flexible tiers of HART and FF device communication modules that are hot swappable, intrinsically-safe and easily changed. The industry changing Trex Device Communication Plus Module provides you the ability to power loop segments, diagnose and measure 4-20mA loops using the built-in ammeter - quickly and intuitively with no additional equipment.
Puts relevant information at the user’s fingertips as soon as the device is connected and offers device information, alerts, device status, primary measurements, and menus all at first glance so the user can easily diagnose the issue at hand.
Maintain data integrity by automatically recording device configuration changes made in the field and synchronizing these changes to AMS Device Manager software creating an accurate audit trail record.
