XC series analog expansions User Manual Page 33 of 53
MANU003R2V1
Each expansions’ input/output have the choice of voltage 0 / 5V, 0 / 10V, current 0 / 20mA,
4/ 20mA modes. Via the setting of special FLASH data register FD inside the PLC, see the
following table:
Module
Channel’s ID
0CH / 3CH
1# module
D8250
2# module
D8258
3# module
D8266
4# module
D8274
5# module
D8282
6# module
D8290
7# module
D8298
The corresponding register’s 4 bits assign each channel’s working mode. Each bit’s definition is
listed in the following table:
