Company Profile

Delta Computer Systems, Inc.

DELTA Logo

Delta is a long-term growth oriented company dedicated to providing expertise in usable forms to industrial customers. Look to Delta for innovative technology, great products, responsive service, and lasting value.

Every major action or direction that Delta takes revolves around these core concepts:

  • Great Technology: unsurpassed combination of engineering theory and application expertise, coupled with a focus on implementing industrial standards.
  • Great Products: high-performance, innovative products to industries that value ease-of-use, quality, reliability and long-term availability.
  • Responsive Service: excellent support and training, before, during and after the sales on legacy as well as newer products.
  • Long Term Growth: independently owned, financially conservative company dedicated to attracting and keeping great people.

At Delta, we recognize that expertise helps no one if it is locked away. So we strive to embed our know-how into our products, training and support and into every function at Delta:

Yet, we realize that our customers need more. Since the useful lifetime of an industrial machine can extend from years to decades, customers need to be confident that their major automation suppliers are dedicated to long term support for their products. Delta’s policy is to avoid obsoleting products as long as there is demand for them.

Also, the combination of products that use PLC-like programming instead of more customized programming methods and extensive training classes makes it possible for OEMs to take greater product ownership, greatly reducing long term costs. And for OEMs that do not have an engineering staff, a large number of systems integrators are trained on Delta’s controllers for more support when needed.

A Brief History of Delta

Systems Experience

In 1982, Delta Computer Systems, Inc was incorporated to provide high-performance electronics controls for industrial applications.

Knowing that industrial customers need stable suppliers for critical technology purchases, Delta’s key goals included serving diversified markets, being fiscally conservative, and providing rewarding job opportunities. (Delta’s continued growth and low employee turnover are results of this focus).

In the early years, Delta successfully completed a variety of projects including electron beam guidance systems for melting titanium and controls for machines that detect and remove defects from French fries. (Delta engineers gained first-hand experience with control systems integration challenges—leading to comprehensive setup and diagnostic tools for Delta’s products and a dedication to responsive support).

The First Delta Motion Controllers

Recognizing an opportunity to simplify control systems by integrating motion control and PLCs, Delta developed its first product, the MC186/40. (It is still available—showing Delta’s commitment to legacy products: do not obsolete as long as demand exists).

Motion product sales grew rapidly in the early 80’s as Delta introduced additional products and expanded into many applications. (Delta doesn’t integrate its own products (to avoid competing with customers), and concentrates on selling through distribution and integrating via OEM’s and control systems integrators).

Delta’s engineers cleverly designed the bus-based motion controllers to plug directly into PLCs and to talk directly to PLC registers, greatly simplifying the integration of these products. In addition, these “Delta cards” connected directly to most industrial transducers, including specialized transducers for fluid power applications.

Delta soon developed a reputation as experts in industrial motion control, with extensive knowledge in specialized areas such as fluid power and pressure control and technical support people that truly care. (Unlike many companies, where tech support is an entry-level function, Delta’s has experienced people available 24/7, backed up with the very engineers that designed the products. This ensures responsiveness and Delta’s products benefit when the designers see them in real applications).

The RMC Families

RMC70 and RMC150

In response to increasing requests for connectivity to additional PLCs, Delta took advantage of the emerging fieldbus technology and developed a motion controller specifically designed to talk to any PLC or host system, the RMC100. Delta’s engineers designed the RMC to “look” like a PLC over the bus, and provided a unique Step Table whereby time-critical sequences could be offloaded into the RMC. It soon became common to hear customers boast that, with the RMC, they were able to complete projects in days that would have taken weeks with other motion controllers.

Color Sensors

CS24D

Delta also developed a series of color sensors aimed at challenging applications in color recognition, especially on textured materials.

Timeline

Delta and Motion Control

Mid-70s

  • Delta Computer Systems was a leader and innovator in using servo hydraulic motion control to precisely position logs, cants, and lumber products for the best and most efficient cut.

Mid-80s

  • Delta introduced its first motion controllers. As the trend toward PLC-based motion control increased, Delta expanded its product offerings with other PLC-bus and open-bus products and added servo electric and position-pressure control capabilities.

Mid-90s

  • Delta introduced the flexible and modular RMC100 Series, designed for use with fieldbus communications. With multi-axis servo electric, hydraulic, and pneumatic control capabilities, Delta’s flagship RMC100 is now quite possibly the most versatile industrial motion controller on earth, with new features being added each year.

Mid-2000s

  • Delta introduced the RMC70 Series, which complements the RMC100 and provides more value for 1- and 2-axis applications. Delta also introduced the new RMC150E CPU for the RMC100 Series.

Future

  • Delta is committed to continue to use its motion control and industry standards expertise to your advantage by providing:
  • —High-performance motion control products that you can use – with the performance you need and connectivity to your PLC and transducers.
    —Valuable training, and knowledgeable, responsive technical support

Delta and Color Sensing

Mid-80s.

  • Delta developed the sensing and control system for a machine that removes defects from French fries. The first two production systems were installed in 1988, and are still being used today. Over time, 11 additional machines were installed; each machine can handle 10,000 lbs/hour of French fries.

Mid-90s.

  • Delta introduced the CS64A, a color sensor based on the sensing technology used in the French fries processing machines. The CS64A offers superior color detection on textured materials, and its analog outputs allow the user to program for as many sort categories as needed, as well as see color trends.

Mid-2000s.

  • Delta introduces the CS24D, with a Teach function allowing up to fifteen colors to be differentiated with one sensor.

Future.

  • Delta is committed to continue to use its color sensing and industry standards expertise to your advantage by providing:
    —High-performance color sensors with the performance you need and connectivity to your PLC.
    —Knowledgeable, responsive technical support
