Process Control Trainer, Downsized

#601D

Larger

This economical, yet realistic, device incorporates the primary functional features of our standard, #601 Process Trainer, Basic, in a space-saving, and flexible package. Allowing for training relating to both field installation and calibration of instruments, and basic control principles, it can be used within a variety of instrumentation, and process technology programs. The trainer allows control loops to be configured employing feedback, feed-forward, and cascade control methods. Variable demand and supply disturbances are easily inserted using solenoid valves in combination with metered ball valves. This arrangement provides step-change disturbances for performing and verifying controller turning. The standard device includes an industrial quality PID controller, differential pressure transmitter, I/P converter and three-valve manifold, allowing for exercises in pressure, level and flow without the need for supplemental or optional equipment. The device's "open architecture" allows for the installation of a broad range of optional equipment to expand the device's usefulness, whether purchased with the device or at a later date. The level tank and piping are transparent, allowing visual inspection of the process. Air supply regulators, and an I/P converter are mounted on the primary frame for convenience. The controller, standard 24 VDC power supply, control relays, and electrical protective devices are located in an independent control module, which tethers to the device. This control module incorporates 19" rack panels for standard instruments and optional devices. Most importantly, the training aid can be outfitted with an wide variety of optional or user-supplied controls and instruments in order to address site-specific training needs.
