Product Overview
Emerson AMS Trex 2 TREX2CHPNA9S3
HART-Only Device Communicator with Soft Case | 3-Year Standard Support | Non-Wireless | Non-IS
The Emerson AMS Trex 2 TREX2CHPNA9S3 delivers the same reliable HART communication as the S1S model but extends your coverage to 3 years of standard support. Ideal for organizations that want long-term software updates, DD driver refreshes, and technical assistance without upgrading to premium repair plans.
What makes this different from TREX2CHPNA9S1S? The “S3” support code upgrades coverage from 1 year to 3 years. You get the same communicator, same soft case, same capabilities — but with extended peace of mind for multi-year projects.
