Product Overview
The Yokogawa ATF9S-00 is a pressure clamp terminal block designed for use in Foundation Fieldbus wiring within Yokogawa FIO (Field I/O) systems. It provides four ports (CH1–CH4) for secure field connections and is typically used with the ALF111 Foundation Fieldbus communication module. The unit is compact, lightweight, and uses spring pressure clamp technology for reliable, maintenance-free terminations.
Advantages
-
4-port design for orderly and efficient wiring.
-
Spring pressure clamp terminals reduce maintenance compared with screw-type terminals.
-
Compact size allows high-density panel installation.
-
ISA G3 environmental compliance for industrial environments.
-
Direct compatibility with ALF111 communication module.
Applications
-
Foundation Fieldbus H1 segment wiring for process automation systems.
-
Control cabinet and marshalling cabinet terminations.
-
Replacement for screw terminals in upgrade projects.
-
Installations requiring vibration-resistant and reliable wiring connections.
