Overview
The AGM Electronics EA-4000-13 isolator is a compact signal converter designed for industrial automation systems requiring galvanic isolation between 0–1 V and 0–5 V input sources and 4–20 mA loop outputs. This isolator is widely used in PLC and HMI installations where sensor signals or control voltages must be isolated and scaled to standard 4–20 mA process control signals.
Key Features
- Galvanic isolation between input and output circuits
- Converts 1/5 VDC input to 4/20 mA output
- Compact, panel-mount or PCB-mount design
- Reliable performance in industrial control environments
- Industry-standard sizing for OEM integration
- Red status indicators for operational feedback
Technical Specifications
- Input: 1/5 VDC (0–1 V or 0–5 V selectable range)
- Output: 4/20 mA DC
- Isolation: Galvanic isolation between input and output
- Output Impedance: Typically 200 ohms nominal
- Supply Voltage: 24 VDC (standard industrial)
