The PR Electronics 4104 Universal Bipolar Transmitter is a precision signal-conditioning module designed for industrial automation and process control applications. It accepts bipolar DC input signals — both voltage and current — and provides a configurable isolated output in either current or voltage format. Built with full galvanic isolation, this transmitter minimizes ground loops and ensures accurate, drift-free performance in electrically noisy environments.
Key Features:
-
Supports bipolar input (e.g., ±10 V or ±20 mA) for flexible control applications
-
Galvanic isolation between input, output, and power supply for clean signal integrity
-
Selectable output: 0–20 mA, 4–20 mA, ±20 mA, 0–10 V, or ±10 V
-
Front-panel zero and span adjustments for easy calibration
-
Excellent accuracy and low offset drift for stable long-term signal conversion
