RS232 to Current Loop 2-wire CLO Converter
ADA-1028L

RS232 to Current Loop 2-wire CLO Converter* The prices are given in the response to the offer.
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.
