ADA-1028L converter allowes to connect devices with
two-wire Current Loop interface (CLO) to the RS232 interface
(eg. the computer or controller) for example, counters such LZQM without interfering with the format of
transmitted data. ADA-1028L converter transmits data at baud rate up to 19.2 kbps via one pair of the Current
Loop twisted-pair cable.
Converter is equipped with screw terminals for connection Current Loop inteface and
power supply.
Device for operating uses only signals:
- Rx, Tx, GND - the RS232 interface,
- TX +, TX-/ CLO-, RX +, RX * +, RX-/ CLO + Current Loop CLO interface.
You can connect up to four devices operating in half duplex mode to the Current Loop bus built on the ADA-1028L.
1kVDC or 3kVDC galvanic isolation and
5kVDC opto-isolation in the signal
channel separates RS232 interface of converter from CLO interface and protects devices connected to the RS232
interface from surges generated on line CLO and power circuit.
The converter has an internal low-energy surge protection for each line of Current Loop interface.
