The external DC power sources need not be derived from
interlock contacts, but by employing interlocked power
sources, the system interlock cabling can be minimized. This
feature is especially useful for guaranteeing the fail-safe
shutdown of select SSR channels in the event of a critical
condition such as emergency stop (ESTOP) activation, open
safety hood, etc.
Figure 58 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 SSR that is configured to use PWR0 will
automatically lose power when either ESTOP contact is
opened, and any SSR that is configured to use PWR1 will lose
power when the hood opens. All other SSRs use the +24V
“always on” power source and thus are unaffected by interlock
contacts. PWR2, PWR3 and PWR4 are not used in this
application.

Use Sensoray cable assembly, part number 2600C1, to connect
P1 or P2 to the power daisy chain
11.2.3 Relay Power Selection Shunt
Each relay channel may be independently operated from any of
the six external DC power sources (that are connected to P17
and P18) by installing the appropriate programming shunt.
A shunt receptacle matrix is provided for each channel. Each
matrix has six shunt positions, corresponding to the six
external DC power sources. As shown in Table 34, a 2mm
programming shunt (supplied with the 2652) must be installed
at the position corresponding to the relay channel’s target
power source. Only one shunt should be installed per matrix.
Each channel’s shunt receptacle matrix is located adjacent to
its SSR socket as shown in Figure 59.

11.2.4 I/O Connectors
The 2652 module employs sixteen connectors for field
wiring. Each channel uses one connector for line and one for
load (see Figure 59).
