Engineering Advantages
- 3-Way Galvanic Isolation: Eliminates ground loops and protects sensitive instrumentation from common-mode noise
- Universal Power Input (MS-DOS): Accepts wide-range AC/DC supply — simplifies panel design and reduces BOM complexity
- 4-Channel Density: Maximizes DIN rail real estate; reduces wiring complexity vs. single-channel isolators
- High Accuracy ±0.1%: Suitable for precision process measurement without additional calibration overhead
- Plug-and-Play DIN Rail: Spring-clamp or screw terminals; no special tools required for installation
- Wide Temperature Range: Qualified for harsh industrial environments from -25°C to +70°C
System Architecture & Signal Flow
The ATR-4D41133-MS-DOS operates as a transparent signal conditioner within the I/O layer of a control system architecture:
- Field Instrument → Analog sensor or transmitter (4–20 mA / 0–10 V) connects to isolated input terminals
- Signal Conditioning → Internal galvanic isolation barrier removes ground loops; signal is amplified and filtered
- Output Conversion → Conditioned signal is re-transmitted as 4–20 mA or 0–10 V to PLC/DCS analog input card
- Power Domain → Universal MS-DOS power supply accepts panel AC or DC bus — isolated from signal paths
This architecture ensures full electrical separation between field wiring, control system, and power supply — a critical requirement in hazardous area and high-noise industrial environments.

Technical FAQ
Q: What does the “MS-DOS” suffix indicate?
A: The MS-DOS suffix designates the power supply variant — this unit accepts both AC (85–265 VAC) and DC (10–30 VDC) input, providing maximum flexibility for panel integration without requiring a separate PSU.
Q: Is the ATR-4D41133-MS-DOS compatible with HART protocol instruments?
A: The ATR series conditions the 4–20 mA analog signal; HART digital communication superimposed on the loop is passed through transparently in most configurations. Verify with the specific application datasheet.
Q: Can this module be used in SIL-rated safety loops?
A: The ATR-4D41133-MS-DOS is not independently SIL-certified. For safety-instrumented systems, consult Acromag’s SIL-rated product line or request a functional safety assessment.
Q: What is the typical lead time for this part?
A: In-stock units ship within 1–3 business days. For out-of-stock items, lead time is typically 2–4 weeks depending on manufacturer availability. Contact us for real-time stock status.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. A CoC and original manufacturer documentation are available upon request for all orders.
