Cresnet® Terminal Block for CAEN Automation Enclosures
The CAEN-BLOCK is a Cresnet terminal block designed specifically for
Crestron lighting and automation systems to link remote enclosures to
the central PAC2 or PAC2M control system. The CAEN-BLOCK mounts at
the bottom of each CAEN enclosure that does not contain a control
system to provide Cresnet and override signal connectivity for CLX-series
lighting control modules. The CAEN-BLOCK serves as a parallel
distribution block for multiple Cresnet cables, and especially provides for
connection of the Cresnet and override signal cables from the central
control system.
Crestron Network Block (CAEN-BLOCK) provides four termination ports
for Cresnet wiring. The unit has two 5-pin connections that provide
communication to the modules. Contact closure signals that produce an
emergency override of the modules are also sent through these
connections
.
When a switch contact closure is received between the “G” connections
and the “L” or “R” connection (R is used in a double-wide enclosure only)
on the CAEN BLOCK, the respective left or right column of modules will
set the lights to the programmed emergency override state.
The CAEN-BLOCK unit is a pass-through device with a Cresnet power
factor of zero.

NOTES: A module terminal block (CLT-series device) must be ordered for each module. The corresponding CLT terminal block
is installed in the enclosure for high voltage wire termination. Each terminal block includes a terminal rail for mounting the
block in the enclosure. Terminal rails and blocks do not occupy a module space within an enclosure.
CAEN-series enclosures are required to install CLX-series lighting modules.
