2.3 Numbering and Functions of External Input/Output Contacts [X] / [Y]
No. of input/output contacts (in octal):
The No. of input and output contacts on the PLC MPU starts from X0 and Y0. The range of the No. varies upon
the number of points on the MPU. For I/O extension units, the No. of input and output contacts is calculated according
to its connection sequence with the MPU.
ES/EX/SS series MPU:
Model DVP-14ES DVP-14SS DVP-20EX DVP-24ES DVP-32ES DVP-40ES DVP-60ES I/O Extension Unit

(24 points)
Y20/30 ~ Y177
(Note)
Note: The input points on I/O extension units start from X20 and output points from Y20, except input points on
DVP-40ES start from X30 and output from Y20; input points on DVP-60ES start from X50 and output from Y30. The No. of
input/output points on the I/O extension units increases by 8’s multiple. If the number of points is less than 8, it will be
counted as 8.
SA/SX/SC serues MPU:
Model DVP-10SX (Note1) DVP-12SA DVP-12SC I/O Extension Unit (Note 2)
Input X X0 ~ X3 (4 points) X0 ~ X7 (8 points) X0 ~ X5, X10 ~ X11 (8 points) X20 ~ X177
Output Y Y0 ~ Y1 (2 points) Y0 ~ Y3 (4 points) Y0 ~ Y1, Y10 ~ Y11 (4 points) Y20 ~ Y177
Note 1: Besides 4DI and 2DO, SX series MPU has also 2AI (12-bit) and 2AO (12-bit) of analog input/output.
Note 2: SX/SA/SC series MPU share the extension units with SS series MPU. The input points on I/O extension units start
from X20 and output points start from Y20. The calculation on the No. of I/O points is the same as that in SS series.
EH series MPU:

Note 1: The output type of 20EH00T and 32EH00T is transistor, among which Y0 and Y2 are high-speed transistor output
(200KHz) and other outputs are normal transistor output (10KHz). The output type of other MPUs with 16/48/64/80 points is
transistor and all outputs are normal transistor output (10KHz).
Note 2:
The terminal layouts of 32EH00T, 32EH00R and 32EH00M are different. See the instruction sheets of EH series
MPU. In 32EH00M, CH0 (Y0, Y1) and CH1 (Y2, Y3) are high-speed differential output.
Note 3:
The start No. of the input and output points on the I/O extension unit resumes from the last No. in the MPU. The start
No. of input points on the I/O extension unit of DVP-16EH and DVP-20EH start from X20 and output points start from Y20.
The No. on the I/O extension unit are in sequence, with max. input point No. X377 and max. output point No. Y377.
