External Wiring Installation
Power
Power for the entire PressCam 8 system is brought in
through connector J7 on the I/O board.
Power for the control board J1 comes from J9 on the
I/O board.
See Drawing #28-105 for the External Wiring Diagram
in this section.
Die Inputs
• All inputs used are optically coupled and can be
either 12 to 24VDC or 120VAC (optional). The
voltage type must be selected before hand.
• Standard setup: all inputs are setup for 12 to
24VDC except for the brake/clutch input which is
setup for 120VAC.
• Terminals 17 & 18 are dedicated for the brake/
clutch signal.
• Terminals 1 to 12 are Die Sensor Inputs and use
the terminal just to the right of 12 as their common.
• Terminals 13 to 16 are Die Sensor Inputs and use
the terminal just to the left of 13 as their common.
• Tie the common terminals to the +12VDC terminal
of J6 for systems with sensors that go to ground
when closed.
Example: Connect the output from all die sensors to
terminals #1 to #12, then connect +12VDC from J6 on
the I/O board to the COM terminal (just below terminal
#12 on the I/O board).
See Drawing #28-105 for External Wiring Diagram in
this section.
LS Outputs (1-11)
• There is space for eleven limit switch outputs and
one counter output, and four fault outputs.
• The fi rst thirteen outputs use either a solid-state
or mechanical relay modules. The solid-state
modules are selected for either AC or DC and for
the proper voltage/current range.
• Determine the output logic you need for your press
control (i.e., Sinking, Sourcing, AC).
• For solid state outputs, the “NO” terminals are
the + positive side, and the “C” terminals are the
-ground side. For relays, all terminals are DRY
contacts and the terminal labels are correct.
• For Sinking DC systems, you must ground the
“C” terminals and your output is provided at the
“N.O.” terminal. When the output LED is on, the
“N.O.” terminal will pull down to ground.
• For Sourcing DC system, you must place a DC
voltage on the “N.O.” terminal (the voltage level
must be within the range written on the module)
and your output is provided at the “C” terminal.
When the output LED is on, the “C” terminal will
provide voltage. This is the fastest and simplest
method of wiring.
• For an AC system using solid state outputs, you
must apply line voltage to either terminal “N.O.”
or “C” and take the output for the other terminal.
• For relay systems, all terminals are DRY and
provide you with simple N.O. and/or N.C.
switches. You can place any voltage and current
(up to 1/2 the relay rating) on the terminals.
See Drawing #28-105 for External Wiring methods in
this section.
Outputs (12-16)
The speed, die fault, and general fault outputs should
be placed in stop circuits of the machine. The counter
output #12 should be placed in an alarm or top stop
input of the machine control.
See Drawing #28-105 for External Wiring and Drawing
#28-106 for Terminal Chart in this section.
