especially useful for guaranteeing the fail-safe shutdown of
select DIO channels in the event of a critical condition such as
emergency stop (ESTOP) activation, open safety hood, etc.
Figure 35 illustrates a system in which PWR0 is connected to
multiple system emergency stop contacts, and PWR1 is routed
through a safety hood interlock contact. Note that all of the
external power sources are daisy-chained from module to
module. Any DIO that is configured to use PWR0 will
automatically lose power when either ESTOP contact is
opened, and any DIO that is configured to use PWR1 will lose
power when the hood opens. All other DIOs use the +24V
“always on” power source and thus are unaffected by interlock
contacts. PWR2, PWR3 and PWR4 are not used in this
application.

P1 or P2 to the power daisy chain
7.2.3 DIO Power Selection Shunt
Each DIO channel may be independently operated from any of
the six external power sources (that are connected to P1 and
P2) by installing the appropriate programming shunt on the
module.
A shunt receptacle matrix is provided for each channel. Each
matrix has six shunt positions, corresponding to the six
external power sources. As shown in Table 17, a programming
shunt must be installed at the position corresponding to the
DIO channel’s desired supply voltage. Only one shunt should
be installed per block.
Each channel’s shunt receptacle matrix is located to the rear of
that channel’s I/O connector.
7.2.4 I/O Connectors
The DIO module employs 48 RJ-12 modular jacks for direct
connection to field wiring, designated J1 to J48.
As shown in Table 18, each jack has five signal circuits: the
shunt-selected interlock power source (PWR) on pin 2,
common ground (GND) on pin 6, and three contiguous DIO
channels (except J24 and J48, which have a reduced number of
DIO channel connections) on pins 3, 4 and 5. Pin signals
labeled “NC” are not connected to any circuitry on the module.
