ABB DAI04 is an eight-channel Freelance analog input module for low-level voltage, Pt100 resistance sensors and multiple thermocouple types. Official ABB data lists five bipolar millivolt ranges from ±19 mV to ±308 mV, a 0 to 1000 Ω resistance range and 16-bit conversion. Supported thermocouples include B, R, S, E, K, J, L, N, T and U. The module uses at least 10 MΩ input resistance and documents range-dependent basic error between ±0.05% and ±0.1%. The supplied ABB unit is identified by part number P 37131-4-0369632.
The DAI04 is designed for ABB Freelance temperature and low-level measurement tasks that require direct connection of millivolt, Pt100 or thermocouple signals. It can consolidate different sensor types in one engineered I/O module while keeping each channel within its configured range. Commissioning requires correct sensor type, polarity, compensation method and channel assignment. The exact DAI04 hardware and project configuration should be compared before replacement. Its broad sensor coverage makes it suitable for legacy process-temperature measurement and maintenance applications.
Acquires configured B, R, S, E, K, J, L, N, T or U thermocouple signals.
Supports wide- and narrow-range Pt100 temperature measurement in Freelance process applications.
Measures bipolar low-level voltage signals across five documented millivolt ranges.
The configured channel is assigned to a millivolt, Pt100 or supported thermocouple input type.
The high-impedance input receives the low-level field signal without changing its measurement class.
The module converts the selected input using 16-bit resolution and the configured measurement range.
The processed measurement is supplied to the Freelance application for monitoring and control.
One module supports low-level voltage, resistance-temperature and multiple thermocouple measurements.
Documented millivolt, Pt100 and thermocouple spans support precise engineering configuration.
The official specification identifies 16-bit measurement conversion for the DAI04 input paths.
Precise and fast operating modes have clearly defined error behavior for commissioning decisions.
DAI04 supports low-level millivolt signals, Pt100 resistance sensors and listed thermocouple types.
The module provides eight analog input channels.
Each millivolt, Pt100 or thermocouple range has its own span and accuracy behavior.
The official note states that the specified error limits are doubled in FAST measurement mode.
Model verification and packing begin immediately, followed by tracking after courier pickup.
Provide the full label, sensor types, channel ranges, quantity and delivery destination.
The company began in Xiamen, Fujian, China, with a four-person team serving selected European and North American automation customers. Early work centered on building product knowledge, dependable sourcing processes, and practical international trade experience.
By 2017, the team had grown to approximately 30 people and established a warehouse for in-stock automation components. The business expanded across Europe, North America, and Southeast Asia while sourcing capabilities widened to include scarce and discontinued industrial automation parts.
In 2026, a wider professional team supports customers worldwide from inquiry through sourcing, order coordination, delivery, and after-sales communication. The company continues to supply popular, hard-to-find, and discontinued automation components while building long-term international partnerships through responsible service.
