Standard Control Panels - General Specifications
STANDARDIZED PLC PANELS
Applicable to All PLC Panel Options
C&E Design's pre-engineered, pre-fabricated PLC control
panels are available with PLC's from a number of different manufacturers.
These panels are available in either expandable or non-expandable versions.
The fabricated assemblies were conceived for use as a
starter kit for the "do-it-yourself" end-user. They are built
customer who is at least fundamentally experienced with PLC systems and qualified to
make a proper hardware selection. These
panels are ready for you to adapt to
your specific application by providing finalized wiring diagrams, connecting
your field wiring, programming and downloading your ladder logic, and commissioning.
Expandable vs. Non-Expandable:
Our "non-expandable" models are designed with the
assumption that the I/O provided is all you will ever need. Although there
is adequate panel space and terminal blocks for adding door-mounted pilot devices,
landing field wiring, etc., it will NOT be practical to add additional I/O to
these models. These models are compact in size and very cost-effective.
In some PLC manufacturers lines, we offer "lower-cost
expandable" and "medium-cost expandable" lines of standard PLC panels.
Like the "non-expandable" models, these will be equipped with adequate
panel space and
terminal blocks for you to add door-mounted pilot devices, land field wiring,
etc. However, they WILL be equipped with empty PLC slots and / or panel
din-rail space for you to add a limited quantity of additional I/O, terminal blocks, relays, etc. as
you may need, now or in the future. Also, some expandable models are
equipped with larger 24VDC power supplies.
Cabinet and Construction:
All our standardized PLC panels are fabricated in standard
NEMA 12/13 enclosures assembled by experienced technicians. Optional price
adders for each enclosure size are listed to change to NEMA 4X Stainless Steel.
All components utilized are top quality and UL-listed (where applicable).
hard-copy wiring schematic is provided with each cabinet ordered. This
schematic details all internal panel wiring, including power circuits, fusing,
I/O wiring, etc. All wires are numbered based on C&E Design's standard
wire numbering scheme. The customer may customize and complete these
diagrams for their specific application(s).
Detailed cabinet elevation /
layout drawings are considered proprietary and are not available. However, all
cabinets are constructed using the same general arrangement. All
incoming power terminals, receptacle and 24VDC power supply are mounted along
an upper din-rail. The PLC components are mounted in the center of the
panel. Either one or two lower din-rails provide mounting for all field
terminal blocks. Covered wireway is provided for all internal and field
wiring. The following image shows a typical panel arrangement.
Each panel is equipped with terminal blocks
and a main circuit breaker for incoming 120VAC power. The main circuit
breaker provides the line input for a number of individually fused branch
circuits. A fused-input convenience receptacle is provided on all
models. Also, a fused-input and output 24VDC power supply is provided on
all models, with the 24VDC wired to jumpered terminal strips.
All PLC I/O points are wired at our shop to
terminal blocks for use in terminating customer-supplied pilot devices or wiring
from field devices. All wiring internal to the panel is factory-tested
for continuity prior to shipment.
