remember to account for the voltage drop across Flyer’s 900-

To PLC or logic interface
Figure 6-11 illustrates Flyer’s bipolar outputs connected to a PLC DC input module. When
the Flyer output is ON, it sources current and drives the PLC logic input to a logic high state.
See Table 6-10 for a listing of possible output signal configurations.

Table 6-10 lists possible ways you can connect Flyer outputs to your automation control circuits. Outputs
OUT0 and OUT1 are bipolar outputs with isolated return lines. For example, if OUT0_A is wired to the
circuit’s high (+V) side, then wire OUT0_B to the low (return) side or you can connect OUT0_B to the
high side and connect OUT0_A to the low side.
Outputs OUT2 through OUT7 share a common return line, OUT2–OUT7_B. When wiring your external
circuit, the common return line, OUT2–OUT7_B is always connected to either the supply’s high (V+)
side or the supply’s low (return). The “A” side of the outputs, OUT×_A, are always tied to the load.
For example, refer back to Figure 5-11. The common return line, OUT2–OUT7_B, is tied to the PLC’

high (V+) side. OUT2_A through OUT7_A are tied to the high side of the load and the other side of the
