Connecting DC display I/O modules
Use input terminals I1 to I12 to connect pushbutton
actuators, switches or 3 or 4-wire proximity switches. Do not
use any 2-wire proximity switches due to the high residual
current.
Input signal voltage range
• I1 to I6, I9, I10
– Off signal: 0 to 5 V
– On signal: 15 to 28.8 V
• I7, I8, I11, I12
– Off signal: < 8 V
–On signal: >8V
Input current
• I1 to I6, I9, I10, R1 to R12: 3.3 mA at 24 V
• I7, I8, I11, I12: 2.2 mA at 24 V
