Switching I/O Inputs to Sourcing
Inputs to I/O card are configured as sinking. 24 Vdc is applied to all HI terminals. To
switch the inputs to sourcing:
1. Disconnect all wires from the I/O card LO terminals, except terminal 24. Do not
remove the blue and white wires from terminals 24 HI and 24 LO.
2. Move the 6-pole jumpers from the HI terminals to the LO terminals.
3. Install the red wire jumpers to connect all 6-pole jumpers together.
4. Connect the red wire from the 25-conductor cable to terminal 1 LO.
5. Connect the remaining wires to the HI terminals.
6.
At the PEJB, connect the red wire to the (−) terminal.
Photoeye Junction Box
The PEJB houses a 24 Vdc power supply, terminal block, and scanner controllers. The
box is typically mounted on the legs of the part ID stand. The part ID cable and the
encoder, conveyor interlock, and photoeyes or discrete scanner controllers are wired
directly to the terminal block as shown in the junction box drawing.
Power Requirements
The junction box contains a 30 watt, 24−28 Vdc power supply. It requires 120−240 Vac, 1
PH, 50/60 Hz, 2A.
Conveyor Encoder Connections
Bring the encoder cable into the junction box through a cord grip at one of the unused
knockouts. Wire the cable to the encoder and the junction box terminal strip as shown on
the junction box drawing in Section 7.
Photoeye Connections
Connect SO cable to the photoeyes and junction box terminal block as shown on the
drawing. Route the cables into the junction box through dust-tight cord grips.
