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.
● Channel Type: 1 in 1 out, 1 in 2 out, 2 in 2 out
● Power Supply: DC20~35V
● 35mm Din Rail Installation
Features
① It can directly isolate the loop signal in the dangerous area from the signal in the safe area; ② It can allow the instrument to be grounded on site, especially there are many protective function circuits, and it allows live maintenance on site; ③ Compared with other devices, analog signal voltage isolator is still very good in signal processing.
