1 If any input IN3 through IN7 is wired to the high side, then all inputs, IN3 through IN7, must be tied high because they share a
common return line.
2 If any input IN3 through IN7 is wired to the low side, then all inputs, IN3 through IN7, must be tied low because they share a
common return line.
Input/Output circuitry
Digital output circuitry
FH Flyer provides eight bipolar optoisolated outputs, OUT0–OUT7, for operating low-current relays or
Programmable Logic Controller (PLC) DC input modules or other parts handling automation devices.
Two outputs, OUT0 and OUT1, have isolated return pins that allow them to function independently as
high-side (current sourcing) or low-side (current sinking) switches. The remaining six outputs, OUT2–
OUT7, share a common return line that allows the user to configure all six outputs as either high-side
switches or low-side switches. Table 6-8 summarizes output pin assignments while Table 6-9 shows
output signal specifications. FH Flyer outputs are able to sink or source 30 mA maximum.

18 OUT1_B *B connection point for OUT1
5 OUT2_A **A connection point for OUT2 Any
17 OUT3_A **A connection point for OUT3 Any
4 OUT4_A **A connection point for OUT4 Any
16 OUT5_A **A connection point for OUT5 Any
3 OUT6_A **A connection point for OUT6 Any
15 OUT7_A **A connection point for OUT7 Any
2 OUT2–OUT7_B **B connection point for OUT2 through OUT7
* Bipolar outputs are not polarity sensitive—you can connect “A” and “B” connection points to either the low side (– VDC or
return) or high side (+ VDC) of your I/O circuit.
** Bipolar outputs are not polarity sensitive—you can connect “A” and “B” connection points to either the low side (– VDC or
return) or high side (+ VDC) of your I/O circuit; however, OUT2–OUT7 share a common return point so outputs OUT2–OUT7
must all connect to either the low side (– VDC or return) or high side (+ VDC) — they cannot be mixed.
