- 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.
Availability, condition, price, and shipping time for DAI05 0336025MR are confirmed during quotation.

- Each two-wire transmitter receives a 14–24 V DC loop supply
- The transmitter supply is current-limited to 40 mA
- The external source must remain within 18–32.5 V DC
- Each 4–20 mA input uses a standard 250-ohm impedance
- 12-bit conversion provides a 5-microampere least significant bit
- The self-scan cycle is 10 milliseconds or slower
- Line-break monitoring supervises each transmitter loop
- Sixteen red indicators identify channel threshold or fault conditions
- Current limiting separates abnormal loop demand from normal 4–20 mA operation
- Powered acquisition of sixteen two-wire 4–20 mA field transmitters
- Supervised process-current loops requiring individual fault indication
- Grouped analog acquisition in ABB Freelance rack systems
