Technical Specifications

Engineering Advantages

Ultra-Compact Modular Footprint: At 80mm high, this compact design maximizes I/O density, making it ideal for environments with limited space.

Proactive System Diagnostics: Built-in self-diagnostic routines monitor module health, identifying potential faults early to minimize downtime.

Scalable Communication Architecture: Supports multiple protocols, allowing easy scaling of I/O or changes in protocol configurations without redoing the entire system.

Industrial-Grade Thermal Management: With efficient heat dissipation, the 200g solid-state unit ensures reliable operation in high-temperature industrial environments.

FAQs

Does the ALU4*D support redundant I/O configurations?
Yes, it integrates into Yokogawa’s dual-redundant FIO architecture, ensuring continuous data acquisition in case of maintenance or fault.

What type of field signals can the ALU4*D manage?
It handles analog (4-20mA), digital (contacts), and pulse inputs, depending on the installed sub-modules.

Is this a genuine Yokogawa part?
Yes, the ALU4*D is 100% Brand New Original, with factory-sealed packaging and serial numbers for traceability.

Does the module require external configuration software?
No, configuration is done through the standard CENTUM VP Engineering Station, where parameters are automatically downloaded once the module is assigned a node and slot number.
