High Precision Acquisition

Supports 4–20 mA, 1–5 V DC standard industrial signals, with acquisition accuracy up to ±0.1% FS, meeting the high-precision requirements of process control.

Redundant Design

Supports dual-channel redundant configuration, with module failure automatically switching without interruption, ensuring continuous system operation.

Self-Diagnosis and Status Monitoring

Built-in STI (Self-Test Interface), real-time diagnosis of channel faults, open circuits, short circuits, overlimits, etc., status displayed through LED indicator lights.

Electrical Isolation

Full Isolation between channels, between channels and system, effectively suppressing on-site interference, protecting system safety. Compatibility

Fully compatible with Honeywell TDC 3000, TPS, and UCN systems, supporting hot swapping (for some versions).

Enhanced reliability

Wide temperature range, high anti-interference capability, long lifespan design, with MTBF > 1 million hours.
