Yokogawa ATSR3D Dual Redundant Pressure Clamp Terminal Block

Product Introduction

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.

FAQ

1. What is the main function of the ATSR3D terminal block?
   The ATSR3D provides dual-redundant pressure clamp connections for RTD and POT sensors, ensuring uninterrupted signal transmission in critical control systems.

2. Which types of sensors are supported?
   It supports Resistance Temperature Detectors (RTDs) and potentiometers (POTs), commonly used in temperature and process measurement circuits.

3. Does it support both AC and DC signals?
   Yes. The terminal block is rated for up to 250 V AC or DC, suitable for a wide range of industrial sensor wiring.

4. What is the maximum current per terminal?
   Each terminal supports 10 A, which allows safe transmission of signals from multiple sensors without overheating.
