ADA-1028L converter allows connecting 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 transmits data at baud rate up to 19.2 kbps via one pair of the Current Loop twisted-pair cable.
Fig 2. Isolation structure 3. INSTALLATION This chapter will show how to connect ADA-1028L to RS232, Current Loop CLO bus and power supply and how to use it. In the purpose of minimization of disruptions from environment is being recommended to: - use multipair type shielded cables, which shield can be connected to the earthing on one end of the cable, - arrange signal cables in the distance not shorter than 25 cm from powering cables.
