Zhuang Diao PLC
The VC401-11 Coupler Module is a critical interface component in Yokogawa's industrial automation systems, designed to provide seamless signal conversion and electrical isolation between field devices and control units. This robust module serves as a reliable bridge in process control applications, supporting various I/O signal types while ensuring data integrity through advanced noise suppression technology. Its compact, rack-mountable design integrates smoothly with Yokogawa's CENTUM VP and other control systems, featuring galvanic isolation up to 1500V AC for enhanced safety in harsh industrial environments such as oil refineries, chemical plants, and power generation facilities.FAQ
1. What is the VC401-11 Coupler Module?
The VC401-11 is a Yokogawa signal conditioning and isolation module designed for industrial automation systems. It provides electrical isolation (1500V AC) and signal conversion between field devices (sensors/actuators) and control systems like CENTUM VP.
2. What are its key functions?
Signal isolation & conversion (prevents ground loops/noise interference)
Hot-swappable (for maintenance without system shutdown)
Self-diagnostics (LED indicators for fault detection)
Wide operating range (-40°C to +70°C)
3.How do I install it?
Power off the system (unless using hot-swap in redundant setups).
Insert into the rack slot (compatible with Yokogawa FCN/FCJ stations).
Secure with screws and connect field wiring per the terminal diagram.
