2.1 Triggering for An External Device
During a test sequence, an external device may require
triggering. This could be either through a relay or direct to an "ENABLE"
input by using a pull-up resistor (Figure 4).
2.2 External Device Trigger Applications
- Batch counting. The trigger is sent to a digital or electrical counter
in order to count the entire batch being tested.
- Conveyor belt. The trigger is sent to a timer that operates a conveyor
belt, which moves passed parts along a production line.
- Robotic arm. The trigger is sent to a PC that controls a robotic arm
that removes tested parts and/or places parts that are ready for test.
