Series 5 Reliant controllers
combine standard (but easily customized) application software packages with user-programmable logic control. Hardware features include:

• Simple two-piece design or
  easy installation and maintenance
• Turbomachinery-specific mix of high-speed local I/O

Series 5 Reliant Controllers work with CCC powerful TrainTools workstations.

Control Program Options
Reliant Controllers can be purchased with a variety of software packages:

• For many applications, we offer standard control programs that combine various machine control functions. This provides the simplicity of traditional, purpose-built controllers.
• When no standard package fits your needs, our TrainTools engineering programs can be used to build a custom control program that combines the required TrainWare turbomachinery control blocks with IEC-61131 sequencing logic. This provides the flexibility of a programmable controller.

In either case, Reliant Controllers are your best turbomachinery control solution for many common applications, including:

• single-section, steam turbine driven compressor control
• two-section compressor control
• multi-compressor load-sharing station and unit control
• single-section, gas turbine driven compressor control
• companion control for multisection compressors
  packaged air compressor control

Simplification and ease of use have been primary goals in the development of these packages. The I/O channels for most signals are preassigned, and seldom-used control features are omitted. If a standard program fits your needs, a minimum of engineering and configuration (other than tuning) is required. Should you need a nonstandard loop combination or special features, Reliant Controllers incorporate the five standard, IEC-61131 programming languages. This means our
powerful TrainTools engineering programs can be used to develop a custom-control program that provides the exact combination of TrainWare machine-control blocks, and sequencing logic you need.

Simplex or Duplex Configuration
Each Reliant Controller consists of only two major assemblies:

• A Base Assembly with a mounting base and field wiring terminal board that can be mounted on a 19-inch rack or flat surface as a single unit that rarely needs maintenance or replacement
• An Electronics Assembly with two handles to facilitate plugging it into and removing it from the base, includes the CPU and I/O circuitry, a local maintenance interface, and an integral power supply

Duplex Controllers use two Electronics Assemblies that plug into a taller Chassis and share the same terminals.With either model, no rewiring is required to replace faulty modules. Mean time to repair is typically less than an hour. If your Reliant Controllers run different control programs, the number of spares you need can be reduced by using a TrainTools Workstation to download their application software before they are put into service.

Multiple Loop Capacity
The Reliant Controller features a 32-bit microprocessor, and a mix of high-speed local I/O designed to accommodate the following:

• 22 analog, 6 frequency, and 16 digital inputs, all with exceptional over- and transient-voltage protection;
• 6 analog and 14 discrete outputs, with analog output isolation provided by plug-in conditioning modules.

A version with conditioned I/O is also available. Reliant Controller with conditioned I/O supports the operation of multiple control applications. It also supports peer-to-peer communication functions that are used to coordinate the operations with other controllers over high-speed communication networks.

Reliant Controllers also provide four electrically-isolated, 4-wire RS-485 serial ports: one for communicating with a TrainTools Workstation, one for communicating with companion controllers,
and two for Modbus communication with a DCS or TrainPanel 500 Operator Interface.

Local Maintenance Interface
The Reliant Controller’s 4x20 vacuum florescent display, thirteen control keys, and five LED indicators provide a basic, local interface for units mounted near your process equipment.The built-in interface can be used to monitor I/O signals, alarms, and operating states.
