Product Description
M•SYSTEM FR-3A-L
The M•SYSTEM FR-3A-L is a compact, high-reliability 2-wire position transmitter designed for industrial process control applications. It effectively converts a potentiometer resistance input, typically from a valve or damper actuator, into a proportional and standardized 4-20 mA DC current signal. As a loop-powered device, it simplifies wiring and reduces installation costs. The FR-3A-L features convenient front-panel accessible zero and span adjustments, allowing for precise on-site calibration to ensure accurate feedback of mechanical position for monitoring and automation systems.
Technical Specifications:
- Input Signal: Potentiometer (Total resistance 100 Ω to 10 kΩ)
- Output Signal: 4 – 20 mA DC
- Power Supply: 12 – 28 V DC (loop-powered)
- Adjustments: Front-accessible Zero and Span adjustment potentiometers (±5% of span)
