The Acromag 330i is a 4-Wire DC Signal Isolator factory calibrated for quick install. Additionally, the advanced circuitry on this product also eliminates the need to re-calibrate as the load changes. As a result, this signal isolator is ideal for field operation since it can withstand extreme ambient temperatures and also has excellent temperature coefficients.
Secondly, this isolator uses transformer isolation to break the electrical path. This is between the transmitted signal, receiving device and power. Therefore, it eliminates ground loops, reduces noise and protects sensitive instruments from transients for more accurate and reliable measurements.

Other outstanding features of the 4-Wire DC Signal Isolators include:
- 3-way isolation; input, output and power circuits which are isolated from each other
- 1500V AC peak isolation (250V AC or 354V DC Continuous) prevents ground loops
- As well as accurate and reliable in harsh industrial environments
- RFI and EMI resistance to reduce effects of environmental noise
- Factory calibrated
- Calibration is independent of load the eliminate load compensation adjustments
- DC power used to carry lower voltages and does not require expensive conduit for safe or easier installation
- Low input burden (1.3V typical), independent of load, prevents overloading of loop
- Also high load compliance drives output load resistance up to 1050 ohms independent of supply voltage
- 25mS quick response time ideal for monitoring and control system
- Zero and span adjustments enable precise calibration
- -25 to 80°C operation
