KW920-SV Current Loop Converter
Product Description
The interface converts NMEA 0183 data from navigation instruments or sensors such as echo sounder & log into a 4 to 20 mA current loop. This is a recognised industrial standard commonly used to drive analogue indicators, data loggers, chart recorders and engine control systems. Voltages +/-10 volts dc and other variants are also used.
The interface can output: –
- 4-20 mA or
- +/-10 volts or
- +/-5v or 0 to+5 volts
| Input | NMEA 0183, RS422 or RS232 via opto isolated channel. |
| 4-20 mA | Output:- Max voltage 10 volts so 500 ohms is the highest value load. |
| Output | Accuracy is typically better than 1%. The current goes to zero if there is no input data. Isolated from power, data and ground |
| Voltage Output | +/- 10 volts for future options. 10K load minimum. |
| Data Outpu | NMEA 0183 for monitoring & test. Bi-colour status LED. |
| Power | 9 to 28 volts DC at less than 200 mA. |
| Housing | Diecast box 222 x 146 x 55 mm. Fitted with cable glands. Removable terminal blocks on the PCB. |
