7 Application Instructions API 50-99 2. The figure below illustrates the external wiring of the 2-array matrix input loop constructed by X40 ~ X47 and Y40 ~ Y41. The 16 switches correponds to the internal relays M10 ~ M17, M20 ~ M27. Should be used with MTR instruction. Must connect to the diode of 0.1A/50V, 1N4148, in series M20 M21 M22 M23 M24 M25 M26 M27 M10: the internal relay corresponding to X41 X42 X43 X44 X45 X46 X47 3. See the figure above. The 8 points starting from X40 start to perform a matrix scan from Y40 ~ Y41 (n = 2). D 2 designates that the start device No.

of the read results is M10, indicating that the first array is read to M10 ~ M17 and the second array is read to M20 ~ M27.
