External I/O Signals for IS-4500CA
PIN NAME DESCRIPTION
1
INT +24VDC OUT
NOTE: Do not use pin 1 unless connecting it to pin 2 or 3. Failure to observe this
precaution will result in malfunction.
MAX CURRENT DRAW: 100mA
2 EXT. COM
For internal Sink (pull down) Connect to pin 1. For Internal Source (push up)
Connect to pin 4.
To activate input in Sink Mode, connect inputs to INT +24VDC GND (I/O COM)
To activate input in Source Mode, connect inputs to INT +24VDC
For External Sink attach PLC +24V. For External Source, attach PLC COM
3 STOP Must be jumpered to Pin 1 to operate. Use relay to provide switch closure if required
4
INT +24VDC GND
(I/O COM) COM pin. This pin is internally connected to the in24VDC GND. NOTE:

WE1 STOP/
PARITY
WE1 stop input or Parity input pin.
When WE1 STOP is selected
Closing this pin during the WELD1 sequence will switch the sequence to COOL1.
The interrupt error occurs when the WELD1 STOP signal is input before the start
signal is input.
When this pin is closed before WELD1 welding start after startup, the current is
supplied for at least a control cycle and WELD1 is stopped to switch the sequence to
COOL1.
When PARITY CHECK is selected
This pin allows for detection of failure resulting from a wire break in the schedule
selection signal lines. Be sure that the total number of closed schedule selection and
parity signal lines is always odd.
