Table 1-1. Available ProTechTPS Models
Applications
The ProTechTPS is designed to be applied as a safety system for any size
steam, gas, or hydro turbine, reciprocating engine, or plant process equipment.
The device's fast response time (8–26 milliseconds depending on model and
configuration), 0.5 to 32 000 rpm speed range, and integrated overspeed and
acceleration detection/protection functionality, make it ideal for applications on
critical low-speed or high-speed rotating motors, compressor, turbines or
engines. This standalone safety device accepts 10 discrete or analog inputs per
module (30 total) and one speed (MPU or PROX) input (3 total). Each
ProTechTPS module provides 3 programmable relay outputs (9 total) and an
analog speed output (3 total) in addition to the trip relay outputs. Configurable
logic allows the customization required to meet specific application requirements
to ensure plant protection.
The ProTechTPS utilizes a triple modular redundant architecture and 2-out-of-3
voting logic to accurately determine unsafe conditions and ensure that no single-
point failure will affect system reliability or availability. With this design, system
failures (switches, transducers, modules) are detected, annunciated, and allowed
to be repaired or replaced while the monitored system continues to operate
on-line.
Alternatively, this standalone safety device can be configured to protect any plant
system or device, and report the system’s device’s status to the plant DCS. The
ProTechTPS control’s versatile inputs, outputs, programming environment, and
communications make it ideal as a safety protection device for use in small
applications that could possibly reach an unsafe state or condition and that must
communicate directly to the plant DCS. The ProTechTPS is designed for critical
applications where both personnel safety and unit availability (operation run time)
is a concern or necessity.
The ProTechTPS is certified as an IEC61508 SIL-3 (Safety Integrity Level 3)
safety device and can be applied as a stand-alone IEC61508-based device or
within an IEC61511-based plant safety system.
