Mechanical Parameters

Overall Dimensions: 100mm (L) × 80mm (W) × 30mm (H), compatible with compact control cabinet installationHousing Material: Flame-retardant reinforced plastic (UL94 V-0 grade), anti-static coating on surface, heat dissipation grooves on edgesWeight: Approximately 0.3kg, adapting to lightweight installation requirementsMounting Method: 35mm DIN standard rail mounting, supporting horizontal/vertical installation without additional fastenersStatus Indication: 16 channel LED indicators (green: signal active; red: channel fault) + 1 system LED (yellow: normal communication)

Environmental Parameters

Operating Temperature: -40℃ to 70℃ (non-condensing environment, compliant with IEC 60068-2-1/2 standard)Storage Temperature: -40℃ to 85℃Relative Humidity: 5% to 95% (non-condensing, compliant with IEC 60068-2-3 standard)Protection Rating: IP20 (module itself, relying on overall control cabinet protection)EMC Compliance: Meets EN 55022 Class A (emission limits) and EN 55024 (immunity) standards, common-mode interference immunity ≥120dBVibration Resistance: 10-500Hz frequency range, 1g acceleration (sine wave), 30 minutes of continuous testing per axis

Product Performance

High signal acquisition efficiency: 16 channels for synchronous acquisition, with a response time of ≤1ms, which can accurately capture fast-switching equipment status (such as production line limit signals) and avoid control logic misjudgment caused by signal delay.

Strong anti-interference capability: 2500Vrms high isolation voltage and common-mode interference resistance design can resist electromagnetic interference from inverters and high-voltage motors in industrial sites, with a signal bit error rate ≤10⁻⁶ in high-interference environments.

Excellent operational reliability: Adopting industrial-grade components and wide-temperature design, the mean time between failures (MTBF) is ≥200,000 hours; supporting hot-swappable functionality, module replacement does not require system shutdown, and maintenance downtime is reduced to less than 5 minutes.

Wide system compatibility: Directly compatible with Metso DNA and DCS 600 control systems, and also compatible with third-party PLCs (such as Siemens S7 series, Rockwell ControlLogix), enabling integration without custom drivers.

Comprehensive diagnostic functions: Channel-level open/short circuit detection can locate a single faulty channel, and fault information is uploaded to the control system in real time; combined with LED indicators, it realizes “visual diagnosis” and reduces the difficulty of fault troubleshooting.
