SMT Rugged ASCII Panel Mount HMI Terminal

Model: SMT

Two Technologies, Inc.

Looking for a rugged, low-cost panel mount terminal? The SMT is a fully functional ASCII terminal designed specifically for industrial applications. The SMT is flexible! Its menu programmable function keys can transmit a user-programmed character, while host equipment has direct control of cursor movement and appearance, clearing all or part of the display. Function key definitions and operating parameters are stored in non-volatile memory. Available I/O configurations Include RS-232 and RS-422 as well as CMOS/LSTTL logic levels.

Like all Two Technologies' products, the SMT is remarkably rugged. The case is molded from Valox® 420, one of the most durable, chemical-resistant materials available today. Proper mounting of the SMT, with the Two Technologies' mounting kit, assures NEMA 4/12 compliance. Securely framed and clamped into place, the keypad surface provides excellent splash resistance and prevents curling or peeling of the keypad overlay. Keypad layout includes a 20-key configuration and is available with standard or custom graphics.

Custom configurations and special options available, including: Custom Default Settings, Displays, Keypad Graphics, I/O Interface, Firmware, Case Color and Logo Tag

Three (3) year warranty included.
