Product Overview

The YOKOGAWA AFF50D-H41201 is a high-performance Duplexed Field Control Unit (FCU) designed for high-availability distributed control systems (DCS). It integrates two synchronized control processors, redundant power management, and redundant communication paths, ensuring non-stop operation for critical industrial processes. The "D" in the model number (AFF50D) signifies its Duplexed (Redundant) architecture, which is critical for ensuring maximum uptime and fault tolerance. The H41201 configuration specifies its capacity, memory, and supported communication protocols.

The AFF50D-H41201 is a vital component for mission-critical applications that demand continuous, high-performance control, ensuring zero downtime through its fault-tolerant design.

Detailed Technical Specifications of the AFF50D−H41201

Duplexed Architecture for Maximum Uptime

The duplexed processor pair is the core feature of the AFF50D-H41201. One unit operates as the active controller, while the other is synchronized and in hot-standby mode, ready to take over at any moment without interrupting the control process. This bumpless transfer ensures that the system maintains operation even in the event of a processor failure.

Additionally, redundant power supplies, communication links, and I/O buses further eliminate single points of failure within the system. The unit also features a high-speed, deterministic control cycle, making it ideal for demanding industrial control environments.

Frequently Asked Questions (FAQ)

Q1: What does "Duplexed" mean for the AFF50D−H41201 FCU?
A1: "Duplexed" means the AFF50D−H41201 contains two synchronized control processors and redundant power/communication paths, ensuring fault tolerance and non-stop system availability.

Q2: Does the AFF50D−H41201 include I/O modules?
A2: The AFF50D−H41201 is the core unit housing the control processors and provides slots for I/O modules. I/O modules must be ordered separately based on specific system requirements.

Q3: What is your typical shipping timeframe for the AFF50D−H41201 unit?
A3: We typically ship within 3 days to 2 weeks, depending on the size and complexity of your specific order. Stock availability is usually ensured.

Q4: What is the main benefit of the AFF50D−H41201 over a standard FCU?
A4: The main benefit is its full redundancy (processors, power supply, and communication), which ensures continuous process control even during hardware failures, resulting in no downtime.

Q5: What is your policy if the unit has a quality issue upon arrival?
A5: We offer a 30-day return window for the YOKOGAWA AFF50D-H41201 module if there are any quality issues upon arrival.
