TB-2 I/O CIRCUITRY
Input _________________
Figure 1-24 Input use external Power supply
Figure 1-25 Input use internal Power supply
All DigiPackⅡ I/O can be uses both POSITIVE/NEGATVIE LOGIC
DigiPackⅡcan be used external and internal power supply. And provide isolated inputs.
The external power supply has an output 24VDC.
The contacts used must have very low contact resistance over a long life time.
Extreme care is required when wiring to insure that ground loops do not exist. Ground loops can cause
damage to the DigiPackⅡand other electronic equipment. Ground loops can also cause erratic operation of
the entire blow molding machine.
Output ___________________
Figure 1-26 Output use external Power supply
Figure 1-27 Output use internal Power supply
DigiPackⅡ’s output circuits use Photo MOS Relay to provide isolation from the external circuitry.
An external power supply is required.
The maximum voltage and current output to each load terminal (TB-2, 18, 19, 20, 21, 22, 23 and 24) is
24VDC and 100 mA MAX/each.
