GENERAL PRODUCT GRADE EXPLANATION
All of our designs can be built three basic ways that make a difference in
the facilities they can be used in and the final price. We build per your
specifications, so these grades are just a general guideline.
Economy Systems -
Commercial and Light Industrial
Many facilities are not particular about the brand or components used. These
systems have name brand components and designs that are very cost effective.
-
Small "Brick" PLC with limits and pushbuttons "ganged" for efficiency.
-
No spare I/O
-
IEC Grade Contactors
-
Terminal Strip Terminal Blocks
-
Wire code by random colors
-
40 VA transformer for Secondary Circuits
-
Main fusing by others
-
Exact size enclosures with no expansion room
Industries
Industrial Grade System -
Heavy Industrial
These systems are for heavy industrial facilities with abusive environments
and high usage. Specifications dictate equipment.
- PLC by specification - each device has an I/O Point
- Minimal spare I/O
- Disconnect on control panel (Rotary or Flanged)
- Main Fuses Included (Class J)
- Enclosure per specification (NEMA 4 or 12 Standard)
- 50 VA Minimum secondary transformer
- 120 volt / 24 volt auxiliary accessory power in panel
- Transformer fuse protected
- NEMA or IEC grade contactors (per specification)
- Euro Style Terminal Blocks
- Class 10 Overloads
- 22 MM pushbuttons and pilot lights - NEMA 4/12
- Wire Colors and Numbering per NFPA-79 (JIC)
- Wire Marker on each end of each wire.
- Component Identification per NFPA-79
- 10% Expansion Room
- Pushbutton and Pilot Light colors per NFPA-79

SAE Automotive/Aerospace
Specification System - Strict Machine Tool Specification
Strict specifications and design standards are followed, while economics are
taken into consideration with each system. Systems range from NEMA Size 1
starters, to the highly efficient IEC Self Protected equipment.
