Product Performance

Adopting 24-bit high-precision A/D conversion chip and low-temperature drift signal conditioning circuit, the full-range measurement error is ≤±0.1% FS, and the measurement resolution of PT100 signals reaches 0.01°C, meeting high-precision parameter acquisition requirements in process industry. Each channel independently supports HART protocol, enabling remote reading of range, unit, fault code and other parameters of intelligent transmitters (e.g., pressure transmitters) via AC 800M controller or ABB Control Builder M configuration software, realizing “non-disconnection configuration” and reducing on-site maintenance workload.

Electrical isolation between channels avoids signal crosstalk; overvoltage protection (≤35V DC) and overcurrent protection (≤50mA) can resist abnormal on-site signal impact, protecting the module’s core circuit from damage. It supports hot-swapping; module replacement does not require turning off the I/O rack power, only needs to activate “offline mode” in the configuration software, and communication is automatically restored after replacement, adapting to 24/7 continuous production scenarios.

Fully compatible with AC 800M series controllers (e.g., PM861, PM864), the data transmission delay is ≤100ms, supporting signal filtering, range conversion and other preprocessing functions on the controller side without additional hardware. The Mean Time Between Failures (MTBF) is ≥600,000 hours (MIL-HDBK-217F, 25°C environment), complying with industrial-grade long-life operation standards.
