4. Functionality
The MDI3201 operates as a signal conditioning interface between a current loop sensor and a voltage-based control system. The module receives a 4–20 mA current signal—a standard in industrial instrumentation representing a process variable such as temperature, pressure, or flow rate. Internally, the module converts this current into a proportional 0–5 V output voltage, maintaining linearity across the entire range.
Working Principle:
1. The input current (4–20 mA) flows through a precision resistor network, generating a corresponding voltage drop.
2. The internal circuitry scales and buffers this voltage to produce a stable 0–5 V output.
3. The output voltage can then be fed into analog input channels of PLCs, controllers, or monitoring systems.
Use Cases and Applications:
- Industrial process control systems
- PLC analog input interfacing
- Data acquisition and monitoring systems
- Sensor signal conversion (pressure, temperature, flow, level transmitters)
