The BA201 communications isolator is a dedicated interface for connecting intrinsically safe BEKA Serial Text [Data] Displays to a safe area computer system. The communications isolator provides intrinsically safe galvanic isolation between the safe and hazardous areas, plus conversion of the RS232 or RS485 safe area serial data to the dedicated communications signaling required by BEKA Serial Text Displays.
The isolator also powers the Serial Text Displays and depending upon the wiring configuration, up to four displays may be connected to each BA201. To prevent earth loops both communications ports are functionally isolated from the BA201 power supply terminals allowing an earthed or floating supply to be used.
Supported by a three year guarantee.
This module used when powering and communicating with BEKA BA484D and BA488C Intrinsic Safe Serial to Text Displays.
