Product Advantages
Ultra-high Accuracy and StabilityIt features a DC signal accuracy of ±0.05% FS, ±0.1℃ for Pt100 RTDs and ±0.2% FS for thermocouples. With 16-bit resolution, low temperature drift and high common-mode rejection ratio (CMRR), it guarantees long-term stable acquisition of critical parameters.
Full Channel Isolation & Strong Anti-interference CapabilityConfigurable for 8 single-ended channels or 4 differential channels. It provides 2500V AC isolation between channels and between channels and ground. Equipped with EMI protection and shielding design, it operates reliably in environments with dense high-power equipment and intense electromagnetic interference.
Multi-signal Compatibility for Simplified System DesignNatively supports 4–20 mA / 0–20 mA, 0–10 V / 1–5 V, K/J/T/E/S/R/B type thermocouples and Pt100/Cu50 RTDs. No additional signal conversion modules are required, cutting hardware costs and wiring complexity.
HART Communication & Intelligent MaintenanceBuilt-in HART protocol enables remote access to diagnostic data, configuration information and process data of smart instruments, reducing on-site inspection work. It supports hot swapping and redundant configuration. Faulty modules can be replaced online without system shutdown to ensure uninterrupted production.
Industrial Durability & Wide Temperature AdaptationAdopts reinforced PCB and industrial-grade components with IP20 protection rating. The operating temperature ranges from -20℃ to +60℃, delivering reliable performance under harsh conditions such as high temperature, humidity and vibration.

Frequently Asked Questions
Q1: No data is received and the RUN indicator flashes.A1: ① Poor bus contact: Re-insert the module and clean the contacts.② Incorrect address configuration: Verify the bus address (0–125) and ensure no duplicate addresses.③ Excessive bus load: Limit the number of modules on a single bus to no more than 32.④ Damaged cable: Replace the bus cable.
Q2: Large temperature deviation occurs on thermocouple acquisition.A2: ① Abnormal cold junction compensation: Check the built-in compensation sensor and enable the compensation function in configuration.② Mismatched type: Confirm the thermocouple type in configuration matches the actual device.③ Oxidized wiring: Clean and retighten the terminal connections.④ Sharp ambient temperature changes: Keep the module away from heat or cold sources to stabilize the ambient temperature.
Q3: Severe fluctuation of 4–20mA signals.A3: ① Poor grounding: Implement common grounding for the module and field instruments to avoid ground potential difference.② Severe electromagnetic interference: Use shielded cables and keep them away from high-interference equipment such as inverters and motors.③ Improper filter settings: Increase the filter time constant in configuration.④ Defective sensor: Calibrate or replace the transmitter.
Q4: Does it support redundancy? How to configure it?A4: It supports 1:1 redundancy. Configuration steps:① Install two DSAI130A modules on the rack.② Enable the redundancy function in configuration and set master and slave modules.③ The system synchronizes data automatically. The slave module will perform bumpless switchover once the master module fails.
Q5: Is hot swapping supported? Is power-off required?A5: Hot swapping is available and power-off is not needed. Simply remove the faulty module and insert a new one. The system will automatically recognize the new module and resume communication without affecting other channels.
Q6: Is it compatible with legacy systems such as Bailey INFI 90?A6: Yes. The DSAI130A can directly replace legacy I/O modules with compatible wiring and enhanced functions, serving as a cost-effective and efficient solution for legacy system upgrades.
