The PSMT is the rugged fully programmable member of Transtech Systems family of panel mount terminals. With the PSMT, you determine how to control your equipment. Using programs developed in "C", Assembler or 2BASIC your applications can be as simple or complex as you make them. The PSMT has a comprehensive applications programming interface (API) that provides full access to all aspects of operation without hardware specific coding. At your discretion, API services can be applied and firmware code blocks intercepted. The PSMT is the ultimate customized operator interface. As with all Transtech Systems terminals, the PSMT is remarkably rugged. Its case is molded from General Electric Valox®420, one of the most durable, chemical-resistant materials available and, when properly mounted, NEMA 4/12 compliance is assured. The keypad surface is securely framed and clamped into place to prevent curling or peeling of the keypad overlay. Stock and custom keypad layouts are available.
