Overview
The RTI-420(2W) is a 2-wire loop powered resistance to current transmitter designed using precision current output converters. It is designed to transmit analog 4 to 20mA signals over an industry standard current loop and provide accurate current scaling and output current limit functions.
Features
- Wide Loop Supply Range: 7.5 to 36 VDC
- 2-wire Loop Powered
- Input Potentiometer: 100 ohm to 10 k-ohm
- Low Span Error: 0.05%
- Low Non-Linearity Error: 0.003%
- DIN-Rail Mountable
Applications
- Positioning Encoding (e.g. Rudder Angle, Valve Position, etc)
- Signal Conversion from sensors with resistance output
