More Information

Overview Manuals Signal Range Conversion Field Wiring Application
  • Sixteen analog inputs for 0–20 mA or 4–20 mA signals
  • Two optocoupler-isolated groups of eight channels
  • Line-break supervision with individual channel indicators

DAI01 Y0369628M is an ABB analog input module designed to acquire sixteen current-loop signals in the Freelance rack system.

Its 12-bit converter scans the channels in 10 ms or slower while the module supervises line breaks and separates the inputs into two isolated groups.

Before installation or replacement, verify the selected current range, channel scaling, group commons, field wiring, shield routing and process conditions.

Description
DAI01 Y0369628M is an ABB 16-channel analog input module for 0/4–20 mA signals in the Freelance rack system.

The module uses two optocoupler-isolated groups of eight inputs, 12-bit successive-approximation conversion, line-break detection and a self-scan cycle of 10 ms or slower.

Before installation or replacement, confirm the DAI01 Y0369628M identity, selected 0–20 mA or 4–20 mA range, field wiring, group isolation, scaling, cable shielding and existing rack configuration.

Technical notes
DAI01 Y0369628M requires confirmation of each channel's 0–20 mA or 4–20 mA range, two-group isolation, field-loop scaling and wiring; mismatched range selection can produce incorrect process values.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can DAI01 Y0369628M replace an existing current-input module without changing the controller configuration?
Only when every channel retains the same 0–20 mA or 4–20 mA range, engineering scaling and group wiring. A range mismatch can produce believable but incorrect process values.
Why can several DAI01 Y0369628M channels fail or drift together even when their transmitters are healthy?
DAI01 Y0369628M separates the inputs into two isolated groups of eight rather than isolating every channel individually. Check the affected group's common wiring and common-mode condition before replacing multiple transmitters.
How does DAI01 Y0369628M report an open current loop?
ABB documents line-break detection and individual red channel indicators. For a 4–20 mA loop, use the reported channel condition together with field measurements to distinguish an open circuit from a process-low signal.
Why can a DAI01 Y0369628M process value shift after module replacement even though the loop current is correct?
The replacement may have been assigned the wrong current range or engineering scaling. Compare the saved channel configuration with the actual transmitter range before recalibrating field equipment.
What should be checked when DAI01 Y0369628M readings become noisy or unstable on long field runs?
Check shield routing, field grounding, group common-mode conditions and cable length against ABB's installation limits. Confirm the current loop at the module terminals before diagnosing the converter.
Can DAI01 Y0369628M be inserted while the rack remains energized?
ABB marks hot insertion as unrestricted for this module. Follow site safety procedures and verify wiring and channel state before insertion; hot insertion does not eliminate process-interlock risks.
Why does a DAI01 Y0369628M overload indication return after the module has been replaced?
A persistent excessive loop current, wiring fault or unsuitable field source can drive the replacement into the same condition. Measure the loop and correct the external fault before reconnecting the channel.
