More Information

Overview Manuals Loop Supply Acquisition Fault Handling Application
  • Sixteen 4–20 mA inputs for two-wire transmitters
  • Integrated 14–24 V DC transmitter supply with 40 mA limiting
  • Two isolated channel groups with line-break supervision

DAI05 0336025MR is an ABB analog input module designed to acquire and power sixteen two-wire 4–20 mA transmitters in Freelance racks.

It combines loop supply, 250-ohm inputs, 12-bit conversion and channel fault indication while separating the inputs into two optocoupler-isolated groups.

Before installation or replacement, verify external supply voltage, loop polarity, transmitter burden, group commons, cable voltage drop, scaling and process interlocks.

Description
DAI05 0336025MR is an ABB 16-channel 4–20 mA analog input module for powered two-wire transmitters in Freelance rack systems.

The module provides 14–24 V DC transmitter supply with 40 mA current limiting, groups the inputs into two isolated sets of eight, and uses 12-bit conversion with line-break supervision.

Before installation or replacement, confirm the external supply, loop polarity, transmitter load, group commons, 4–20 mA scaling, cable shield and rack power budget.

Technical notes
DAI05 0336025MR requires confirmation of the 18–32.5 V external supply, loop polarity, two-wire transmitter burden, grouped commons and 4–20 mA scaling; wiring errors can current-limit multiple field loops.

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 DAI05 0336025MR directly replace a passive current-input module?
Not without checking the loop design. DAI05 0336025MR supplies two-wire transmitters, so confirm whether the existing loop expects module-provided power, the polarity and the transmitter burden before transferring wiring.
Why can all DAI05 0336025MR transmitter loops remain dead after an otherwise correct module replacement?
DAI05 0336025MR depends on an external DC source for transmitter power. Check the external supply at the module under load, its polarity, protection and common connections before blaming the field transmitters.
How does DAI05 0336025MR protect a transmitter loop from excessive current?
The transmitter supply is current-limited to 40 mA. If a loop reaches the limit, inspect wiring, polarity and the field transmitter instead of treating it as a normal process signal.
Why might eight DAI05 0336025MR channels fail together while the other eight continue operating?
The sixteen channels are arranged as two isolated groups of eight. Inspect the failed group's supply and common wiring before replacing the module or disturbing transmitters in the healthy group.
How can a technician distinguish a broken DAI05 0336025MR loop from a genuine low process value?
Use the individual channel indication together with a loop-current measurement and transmitter-power check. DAI05 0336025MR provides line-break supervision, so an open or unpowered loop should not be treated as normal process minimum.
Why can a correctly wired DAI05 0336025MR transmitter under-range on a long cable run?
Cable voltage drop can reduce the transmitter's available supply margin even within the documented distance limit. Check loaded loop voltage, transmitter burden, cable resistance and shield routing at the actual installation.
Can DAI05 0336025MR be replaced with the rack energized?
ABB marks hot insertion as unrestricted, but the external transmitter supply and live process loops remain present. Apply site safety procedures and control the process effect before removal.
