Isolated Safety Barrier, BM200
Request a Quote
The 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.
