Product Overview
The AFV30D-A41262/HKU is a high-availability Field Control Unit (FCU) designed for use within the Yokogawa CENTUM VP control architecture. Engineered for mission-critical industrial environments, this unit employs a dual-redundant configuration for both its processor modules and power supplies, ensuring continuous operation even during hardware failures. The /HKU (Housekeeping Unit) option adds advanced environmental monitoring capabilities, including temperature, fan speed, and door status, for enhanced system reliability and predictive maintenance.
Technical Specifications
| Parameter | Specification |
|---|---|
| Processor Redundancy | Dual CP461 processors in "hot-standby" duplexed mode for bumpless switchover |
| Housekeeping Function (/HKU) | Integrated cabinet environment monitoring (temperature, fan speed, door status) |
| Power Supply Configuration | Redundant power via PW481 (100-120V AC), PW482 (220-240V AC), or PW484 (24V DC) |
| Network Communication | Dual-redundant Vnet/IP ports (1Gbps) for synchronization across the plant network |
| I/O Support | Interfaces with FIO modules via ESB or ER bus cables |
| Memory Protection | Battery backup for RAM retention (up to 72 hours); requires 48-hour recharge cycle |
| Mounting | 19-inch rack-mount (5U height) |
| Dimensions (H×W×D) | 221 mm × 482.6 mm × 440 mm |
| Weight | 8.5 kg |
Application and Environment
The AFV30D-A41262/HKU is commonly used in large-scale, high-reliability industrial environments, including:
-
LNG terminals
-
Chemical refineries
-
Power generation facilities
Its primary role is to execute complex PID loops and sequential control while maintaining constant communication with the Human Interface Station (HIS). The /HKU option is especially useful in remote or unmanned environments, where monitoring the health of the control cabinet is critical for predictive maintenance.
Technical FAQ
What is the significance of the "A4" prefix in this model?
The "A4" designation typically refers to the specific power supply and cabling arrangement (e.g., dual-redundant 100-120V AC power) and the 19-inch rack-mount interface used for the FCU chassis.
Can the AFV30D-A41262/HKU be used in a non-redundant configuration?
While the unit could theoretically operate in a single-processor mode, it is specifically designed for duplexed operation to ensure high availability and fault tolerance. Using it in non-redundant mode would compromise the core reliability and benefits of the CENTUM VP architecture.
