Core Functions
Signal Conversion & Adaptation
- Input: Compatible with analog signals (4–20 mA, 0–10 V) and digital signals (dry contact / wet contact).
- Output: Standard industrial signals (4–20 mA, 0–10 V, relay dry contact). It features a conversion accuracy of ±0.1% FS and a response time of less than 1 ms, fully meeting the requirements of real-time closed-loop control.
Electrical Isolation & Anti-Interference
Adopts three-way isolation (input / output / power supply) with a isolation voltage of 2500 Vrms. It effectively blocks ground loop current, surge voltage and electromagnetic interference, protects upstream and downstream equipment, and optimizes the overall EMC performance of the system.
Protocol Conversion & Communication Bridging
Supports mainstream industrial protocols including Modbus RTU/TCP and EtherNet/IP, realizing interconnection between CCC Extreme Eng CPUs and third-party PLCs, DCS systems and remote I/O modules.
As a transition bridge for legacy and new CPU platforms, it facilitates the upgrade of outdated systems (e.g., CCC Legacy CPU) to modern architectures without full hardware replacement, greatly reducing downtime and renovation costs.
Modular Expansion & Hot-Swap Support
Designed for standard 35 mm DIN rail mounting and supports hot swapping. Modules can be replaced and maintained online without disrupting system operation.
It is perfectly compatible with other CCC control modules (I/O modules, communication modules, etc.) to allow flexible system expansion.
