Yokogawa ATSR3D Dual Redundant Pressure Clamp Terminal Block

The Yokogawa ATSR3D is a dual-redundant pressure clamp terminal block designed for high-reliability industrial applications. It provides secure and stable connections for RTD (Resistance Temperature Detector) and potentiometer (POT) inputs, ensuring accurate signal transmission in critical control systems. The dual-redundant architecture allows continuous operation even if one connection path fails, making it ideal for safety-critical and high-availability systems such as Distributed Control Systems (DCS), safety instrumented systems (SIS), and process automation networks.

The ATSR3D integrates a tool-free pressure clamp mechanism, which guarantees strong contact, prevents loosening under vibration, and simplifies installation. Its compact, flame-retardant housing and corrosion-resistant contacts deliver long-term reliability in harsh industrial environments.
