Engineering Advantages
-
Robust Signal Isolation: The module features a 1500 V AC withstanding voltage. This high dielectric barrier prevents ground loops and protects sensitive DCS backplane electronics from field-side electrical surges or high-potential differences.
-
Integrated HART Pass-through: The ASR133-S00 supports bidirectional HART communication. This allows maintenance teams to perform remote calibration, range adjustments, and health monitoring of field instruments directly from the control room, significantly reducing the need for onsite handheld communicators.
-
High-Speed Data Processing: With a 10 ms data update period, the module provides near-instantaneous process feedback. This rapid sampling proves essential for high-speed control loops where even minor delays in signal processing can lead to system oscillation or instability.
-
Simplified Wiring Architecture: The module utilizes pressure clamp terminals. This screwless design maintains constant tension on the field wires, effectively resisting the vibration-induced loosening common in heavy industrial environments like refineries or chemical plants.
FAQs
How does the ASR133-S00 handle 2-wire vs. 4-wire transmitters?
The module accommodates both configurations. For 2-wire transmitters, the ASR133-S00 provides the necessary power (at least 16V DC). For 4-wire transmitters, the module manages the signal input while handling a maximum normal mode voltage of 25V applied to the terminals.
Can I replace a standard AS1133 module with the ASR133-S00?
Yes, the ASR133-S00 provides the added benefit of HART communication. If your existing system uses the same backplane architecture, this module offers a direct upgrade path to enable digital device management without changing your physical wiring.
What happens to the input resistance when the system power is OFF?
To protect the field loop, the module switches to a high-impedance state (1 M$\Omega$ or larger) when powered off. This ensures the module does not load down or interfere with other devices in the signal loop during maintenance shutdowns.
Is this a factory-sealed unit?
Absolutely. We provide only 100% Brand New Yokogawa hardware. Each ASR133-S00 arrives in its original anti-static factory packaging with an intact serial number to guarantee authenticity and a full manufacturer-rated service life.

Tech & Buying Guide
Evolving SCADA System Architectures in Industrial Automation
A robust Supervisory Control and Data Acquisition (SCADA) system serves as the heartbeat of modern industrial operations. Understanding SCADA system architecture is vital for engineers designing efficient control systems. These architectures have evolved from isolated, monolithic structures to highly interconnected, networked ecosystems. Choosing the right design requires balancing data visibility, processing power, and long-term scalability requirements.
Choosing the Right Controller: PLC vs. Motion Controller in Industrial Automation
Selecting the optimal control architecture is a foundational decision in industrial automation. Engineers must frequently choose between a Programmable Logic Controller (PLC) and a dedicated Motion Controller. While both systems manage machinery, their underlying design philosophies differ significantly, impacting performance, scalability, and system integration.
Mastering PLC Power Supply Architectures and Operating Voltages
Selecting the correct operating voltage is a critical step in designing reliable industrial automation systems. Whether you are working with a compact PLC or a large-scale DCS, your power architecture dictates the system's longevity.
