Core Functions
Signal Conversion and AdaptationAs an intermediate connection unit between field devices (sensors, actuators, etc.) and I/O modules of Yokogawa automation systems, it enables reliable conversion of digital and analog signals. It is fully compatible with the signal interface specifications of specific Yokogawa modules to ensure distortion-free signal transmission. Meanwhile, it supports signal configuration for single-channel or redundant-channel setups, satisfying application requirements across different safety integrity levels.
Electrical Safety ProtectionIntegrated with Weidmüller professional terminal block technology, it features a misconnection-prevention and loosening-prevention design. The terminals deliver low and stable contact resistance, effectively suppressing signal fluctuations caused by poor contact. For certain models, mounting positions for overvoltage and overcurrent protection components are available as options, which provide bidirectional electrical protection for system modules and field devices, reducing the risks of faults such as surges and short circuits.
Easy Installation and MaintenanceIt supports quick mounting on 35mm DIN rails compliant with EN 60715 standards. Its modular structure allows fast plug-and-play connection with system modules, eliminating the need for complex wiring work. Each channel is equipped with clear identification and status indicators (e.g., LED indicators, available on selected models), facilitating on-site personnel to quickly locate faulty channels and minimize system downtime for maintenance.
Harsh Environment AdaptabilityConstructed from industrial-grade materials with a special surface coating, it complies with the ISA S71.04 G3 corrosion resistance standard. It can operate stably in industrial environments with temperatures ranging from -20℃ to +70℃, and also demonstrates excellent vibration resistance and electromagnetic interference immunity. This enables long-term reliable operation under harsh working conditions such as dusty and humid environments, ensuring continuous production in process industries.
System Compatibility ExpansionIt is not only compatible with Yokogawa mainstream DCS and Safety Instrumented Systems (SIS) but also can meet the connection requirements of on-site cables with different wire gauges by adapting to various terminal types (e.g., screw-type, spring-type). This enhances the flexible adaptability of the system and reduces compatibility risks during system integration.
