Note 1: The output type of 20EH00T2 and 32EH00T2 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 output type of 40EH00T2 is transistor, among which CH0 (Y0, Y1), CH1 (Y2, Y3), CH2 (Y4) and CH3 (Y6) are
high-speed transistor output (200KHz). The output type of other output points is normal transistor output (10KHz).
Note 3:
The numbering of the I/O points on EH2 series MPU is the same as that of EH series MPU.
SV series MPU:
Model DVP-28SV (Note 1) I/O Extension Unit (Note 2)
Input X X0 ~ X17 (16 points) X20 ~ X377
Output Y Y0 ~ Y13 (12 points) Y20 ~ Y377
Note 1: The output type of 28SV11T is transistor output, among which CH0 (Y0, Y1), CH1 (Y2, Y3), CH2 (Y4) and CH3 (Y6)
are high-speed transistor output (200KHz); others are normal transistor output (10KHz).
Note 2:
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.
Input Relay X0 ~ X377
The numbering of input relays (or input terminals) is in octal form. EH series MPU can have up to 256
points and the range is: X0 ~ X7, X10 ~ X17, …, X370 ~ X377.
Output Relay Y0 ~ Y377
The numbering of output relays (or output terminals) is also in octal form. EH series MPU can have up to
256 points and the range is: Y0 ~ Y7, Y10 ~ Y17, …, Y370 ~ Y377.
Functions of input contact X
The input contact X is connected to the input device and reads the input signals into the PLC. There is no
limitation on the times of using contact A or B of input contact X in the program. On/Off of the input contact X
only changes with On/Off of the input device. You cannot use the peripheral devices (HPP or WPLSoft) to force
On/Off of the input contact X.
The special relay M1304 in SA/SX/SC/EH series MPU allows the peripheral devices HPP or WPLSoft to
force On/Off of the input contact X, but the PLC will not be able to receive external input signals at this time.
Functions of output contact Y
Output contact Y sends out On/Off signals to drive the load connected to output contact Y. There are two
types of output contacts, relay and transistor. Thereis no limitation on the times of using contact A or B of output
contact Y in the program, but the No. of output coil Y can only be used once in the program; otherwise
according to the scan principle of the PLC program, the output status will be determined by the circuit of the last
output Y in the program.
