Yokogawa NFTA4S-10 Pressure Clamp Terminal Block

Overview

The Yokogawa NFTA4S‑10 Pressure Clamp Terminal Block serves as a secure field-wiring interface for connecting external devices such as control valves, actuators, and indicators to the module’s 4–20 mA analog output channels. Its spring-clamp design ensures vibration-resistant connections, eliminates the need for screw tightening, and provides long-term reliability in industrial environments.
