Functional Features
Redundant Design: As a dual – redundant rear – mounted rack, it is equipped with two hot – swappable power supplies, two hot – swappable CPUs, and two hot – swappable communication modules. This design ensures that even if one of the modules fails, the PLC can still continue to operate, providing high availability and fault – tolerance capabilities for critical industrial applications.
Easy Installation and Maintenance: The rear – mounting design makes installation and maintenance more convenient, saves space, and facilitates operation and maintenance by operators.
Strong Compatibility: It is compatible with the GE Fanuc 90 – 70 series PLC systems and can support up to 17 I/O module slots, which can meet the needs of various industrial automation systems.
Stable Data Transmission: If it is the VME bus interface module version, it can achieve smooth data exchange in the VME bus system. It uses advanced VME technology to ensure high – speed data transmission and reliable communication between different industrial components.
Adaptability to Harsh Environments: It has a durable structure and can withstand harsh conditions common in industrial environments, such as a wide temperature range, humidity changes, vibration, and impact. Its operating temperature is generally 0℃ to 55℃, the storage temperature is – 40℃ to 85℃, and the humidity range is 5% to 95% (without condensation).
Support for Hot – Swapping: It allows the module to be plugged and unplugged while the system is running without causing system interruption, which facilitates system maintenance and upgrading and reduces downtime.
Built – in Grounding System: It enhances the safety of the system, helps prevent electrical interference and faults, and protects equipment and personnel.

Technical Parameters
Dimensions: Width is 19.00 inches (483 mm), height is 11.15 inches (283 mm), and depth is 7.5 inches (190 mm).
Power Supply: It supports a variety of power inputs, such as 100 – 240V AC or 125V DC. The maximum 5V current varies according to different power specifications, such as 20A (for 100W 120/240V AC or 125V DC power supplies).
I/O Reference: User – configurable, no module jumpers or DIP switches are required.
Rack Identification: There are four jumpers behind each rack power supply for rack identification.
