1 General
Series BM200 isolated safety barrier can transmit signals between the safe area and the dangerous area, and limit the energy transfer from the safe area to the dangerous area caused by the fault. The voltage, current, temperature, resistance signals generated by the equipment (transmitter) on the dangerous side are isolated and converted into corresponding linear voltage and current signals outputting to the safe area. The product requires independent power supply, and the input/output/power supply is isolated. It can be used in current source, two-wire, three-wire transmitter equipment.

6 Precautions 6.1This product complies with GB3836.1-2010 “Distributor for use in industrial-process measure and control systems–Part 1:General technical specification “and GB3836.4-2010 “Explosive atmospheres–Part 4:Equipment protection by intrinsic safety i “standards, and installation, operation and maintenance should be carried out under the requirements of corresponding standard. 6.2 This product must be installed in a safe area, and the surrounding air does not contain any medium that is corrosive to chromium, nickel and silver plating. 6.3 All instruments connected to the safety barrier must be instruments with explosion-proof certificate. When the safety barrier and a primary instrument form an intrinsically safe explosion-proof system, they must be approved by the state-specified explosion-poof inspection. 6.4 When the wiring is not completely disconnected, it is strictly forbidden to use a megohmmeter to directly test the insulation parameters between the terminals, otherwise the internal fast fuse will be blown. 6.5 The wiring of the intrinsically safe side power supply of the safety barrier should not be mixed with other non-intrinsically safe side circuits. Any wrong wiring may cause danger. The circuit wiring of the intrinsically safe and non- intrinsically safe of this product should be laid separately in the line groove.
