The multiplication operator belongs to the electric combined instrument panel; multiplication can be easily implemented in DCS and PLC systems. When the multiplication operation is to be carried out by an instrument, the SWP-202SX-B-B1-12/12-B-D type multiplication operator should be used. This article shares the method for calculating the output value of a multiplier. The operation principle of the multiplier is that the percentage of the output signal equals the product of the percentages of the two input signals. That is, in the URL http://yunrun.com.cn/upload/201905/22/201905222000522785.png, S0 represents the output signal of the multiplier ； S1 and S2 are the input signals to the multiplier, respectively ； Smax and Smin represent the maximum and minimum values of that signal, respectively (Note: For example, if the signal is in the 4-20mA range, then Smax=20 and Smin=4). Example of calculating the output value of a multiplier: The multiplier operates using a 4-20mA signal format; the two input signals are 12mA and 8mA respectively. What is the output of this multiplier? By substituting the relevant values into the formula above, we get S0 = ÷(20-4) + 4 = 6 mA. The calculation process for the output value of a multiplier is relatively simple; however, many instrument technicians fail to pay attention to the specific method used to calculate this output value.
