BEKA has made it easier to use its range of intrinsically safe serial text displays through the introduction of the new BA201 communications isolator. The dedicated interface provides intrinsically safe galvanic isolation for power and data, plus conversion of safe area serial data into the two or three wire power and communications signalling system required by BEKA serial text displays, which are designed to display text and graphics in hazardous areas. These displays incorporate pushbuttons plus two solid state outputs and include Modbus protocol making them ideal as a low cost operator interface for simple hazardous area machine and process control applications. The field mounting BA484D has a robust IP66 GRP enclosure and the BA488C provides the same functions in a panel mounted format.
Galvanic isolation provides intrinsically safe communication platforms
The BA201 has RS232 and RS485 safe area ports enabling multidrop display systems to be constructed. Depending upon wiring configuration, up to four BA484D or BA488C serial text displays may be connected to each isolator. Isolator configuration is not required, since the unit automatically operates at the required communication rate and detects which of the two safe area ports is being used. Electrical isolation between input, output and the power supply allows the device to be powered from any earthed or floating 20 to 35 V d.c. supply. The communications isolator has ATEX and IECEx IIC intrinsic safety certification, plus FM and CFM intrinsic safety approval for North American installations. The associated apparatus approvals allow installation in a safe area and provide the ability to power and communicate with serial text displays located in any hazardous area zone or division.
The enclosure is designed for DIN rail mounting allowing easy installation alongside other galvanic isolators and Zener barriers. Four green LEDs indicate the isolator status showing when power is connected and when data is being received or transmitted.
