III. Main Functions

16-channel 4-20mA analog signal centralized collection and connection;

Filtering, shaping, and anti-interference conditioning of on-site instrument signals;

Built-in lightning surge protection to prevent high-voltage cross-loss to system cards;

Group-level electrical isolation to suppress common-mode interference, ensuring more stable signals;

Supports online maintenance, with single-channel failure not affecting other circuits.

IV. System Compatibility and Model Interchange

Compatible Controller: HPM, APM Process Manager

Compatible Card: UCN Series Analog Input AI Card

Direct Interchange: 51204162-125 (MU-TAIY52), fully compatible hardware and software can be directly replaced

V. Installation and Usage Tips

Use shielded twisted-pair cables for analog signals, separate from power cables for separate wiring;

Single-ended grounding of the shield layer to avoid multi-point grounding forming circulating interference;

Secure terminal connections, distinguish positive and negative and common lines;

Suitable for chemical, power, and petrochemical process parameter collection.
