Nokeval 6720 Galvanically Isolated 2-Wire Transmitter
Precision 4-20 mA signal isolator/transmitter with sensor break monitoring — lot of 2
Overview
This lot includes two Nokeval 6720 Galvanically Isolated 2-Wire Transmitters, designed to provide accurate, isolated 4-20 mA signal transmission for industrial process instrumentation. With high resolution, sensor break monitoring, and configurable serial communication, these units offer reliable signal isolation and conditioning for a range of measurement applications.
Key Features
- 2-wire 4-20 mA output: Supports straight and reversed 4-20 mA / 20-4 mA operation.
- High resolution: Better than 0.03% of span.
- Output limiter: 24 mA limit for signal protection.
- Sensor break monitoring: Configurable at 3.5 or 24 mA.
- Strong galvanic isolation: 2000 VDC for 1 minute.
- Configurable via serial connection: RS232 at 1200 or 9600 bps using Meku 1 protocol.
- High-resolution conversion: 16-bit A/D converter and 12-bit output DAC.
