Table 3-II MPC I/O Connector Signals
MPC I/O Connector Pinout
The
MPC I/O
connector is a two-piece pluggable termi-
nal block connector.
Table 3-II lists the signal names and descriptions, with 
more detailed descriptions listed below. 
Pin 1 (Setup Bit 0 Input)
Setup Bit 0 is the least significant bit used to select differ-
ent probe channels when a Multi-Probe Control (MPC) 
Interface is used. This MPC control bit is used on all 
MPC systems.
Pin 2 (Setup Bit 1 Input)
Setup Bit 1 is the second least significant bit used to se-
lect different probe channels when a MPC Interface is 
used. This MPC control bit is used on MPC systems with 
three or more channels.
Pin 3 (Setup Bit 2 Input)
Setup Bit 2 is the third least significant bit used to select 
different probe channels when a MPC Interface is used. 
This MPC control bit is used on MPC systems with five 
or more channels.
Pin 4 (Setup Bit 3 Input)
Setup Bit 3 is the second most significant bit used to se-
lect different probe channels when a MPC Interface is 
used. This MPC control bit is used on MPC systems with 
nine or more channels. 
Pin 5 (Input Common)
[Electrically connected to
Pin 13 on System I/O connector.]
Pin 5 is electrically isolated from chassis ground. Using 
sourcing (PNP) output drivers, this common line would 
be connected to the automation system ground potential. 
Using sinking (NPN) output drivers, this common line 
would be connected to the automation system positive 
supply voltage output. Refer to Section 6 for wiring 
examples to connect input signals.
Pin 6
(MPC Ready Out)
Pin 6 is a non-isolated digital NPN status output that 
activates when the MPC control is ready to accept 
changes on the probe selection control bits and ready to 
start the next MPC welding cycle. This output will be an 
open circuit when the MPC system is not ready to accept 
changes to control input signals, and it is able to switch a 
sourcing PNP input ON or OFF.
Any changes will be ignored until this status output signal 
activates to the ready state. This status output signal will 
also be open (MPC NOT READY) if a fault condition 
is detected inside the MPC system. If this status output 
will not activate, check for a RED fault status indication 
(
SYSTEM STATUS
LED
) on the front panel of the MPC
module.
Pin 7
(Output Common)
Pin 7 is connected to chassis ground. The non-isolated 
NPN status output signal can drive an isolated PNP input 
on the automation control system.
Refer to Section 6 for wiring examples to connect output 
signals.
NOTE
The Input Common Pins: Pin 13 of the 
System I/O connector and Pin 5 on the 
MPC I/O connector are both electrically 
isolated from chassis ground, but they 
are connected together. Both of these 
signals must be connected to the same 
voltage potential, either automation 
system ground or the automation sys-
tem positive supply voltage.
