22 IN2_LO **Low (–V) connection point for IN2
23 IN3_A *A connection point for IN3
24 IN5_A *A connection point for IN5
25 IN7_A *A connection point for IN7
* Bipolar inputs and 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.
** High-speed (encoder) inputs IN1 and IN2 are polarity sensitive. Connect the high, or positive, side (+ VDC) to the HI connec-
tion point. Connect the low, or return, side (– VDC) to the LO connection point.
Input/Output circuitry
In15 VDC supply
An internal 15-volt (+15 VDC, 400 mA) isolated power supply is available to drive FH Flyer inputs or
outputs in lieu of a customer-supplied power source. When powering input/output devices or tracking
components such as part sensor and position encoder hardware, remember that the total current
demand of these devices cannot exceed 400 mA. Table 6 -3 summ15 VDC pin assignments.

DB-25 Pin # Signal Name Signal Description
1 + 15 V In15 VDC, 400 mA I/O power supply
14 + 15 RTN Return point for internal 15 VDC supply
Digital input circuitry
FH Flyer provides eight optoisolated inputs, IN0–IN7, for connecting to external input devices including
part sensors, position encoders, relays, and Programmable Logic Controller (PLC) DC output modules.
Table 6 -4 summarizes input pin assignments.
