Chapter 7 : Model 2610 Digital I/O Module

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.
