Electric Distribution
Link-Max LM-P11, LM-P22 current loop with electrical isolation (also known as electrical distribution安全栅) with single-or dual-channel complete separation of functions (meaning complete separation of the output are input loop circuit between the auxiliary power supply completely isolated ), the user can probe to the passive, passive transmitter, power supply passive sensor, it can change them into the signal before and after the isolation, input-output circuit of a high degree of unity 4 ~ 20mA signal can be easily instrumentation and achieve full separation between the equipment. Because of complete separation of input and output channels to avoid interference with a common mode of measurement precision, but also to avoid the potential of the equipment of different hazards. Product achieve full-scale one-thousandth of the precision and linearity, 50ppm temperature coefficient, can provide users with stable and accurate physical isolation and conversion. In some applications, may be no need for isolation, but the output impedance of the instrument is limited, can not promote the high input impedance of the apparatus, then this product is also required to provide impedance transformation.
The input impedance as low as 100 Products in Europe, can cope with any instrument, and the output can push the load 300 in Europe.
Current loop with electrical safety instrumentation Fence for supporting the design of industrial applications. Widely used in power systems, petro-chemical system, the metal system of coal mining, sugar refining and other industrial environments.

The application of this product are passive in front of the probe, passive sensors, passive instrument of the situation, if the front of the device are active and can have 4-20mA current input to the input of the back of separation can use LM-11 single road, or LM-22 two-way passive安全栅separation. LM-11 is an input from circuit-based electricity, the use of the product without external auxiliary power supply, but must have the actual current flows.
The Company also produces many active input and output current loop road separation distribution can be used in place need to be more accurate.
If users need to access more isolated, may choose to LM-P22 with dual-channel electrical isolation安全栅, the product integration in a case of road two LM-P11, to enable users to install a higher density.
