4.1.7. Opto-Isolated Inputs (TB305)
The inputs are configured for 5-24 volt logic, using a higher input voltage, requires
adding external series resistors to limit the current. The opto-isolator is a PS2506L-4
device. The inputs may be connected to current sourcing or current sinking devices, as
shown in Figure 4-11 and Figure 4-12. Each 4-bit bank of inputs (0-3 or 4-7) must be
connected to either all current sourcing or all current sinking devices. Also, note in the
table below, that inputs 0-3 and inputs 4-7 have two different common inputs, pin 1 and
pin 2, respectively. See Section 3.3.1 for opto-isolated EOT limit inputs.
