ProTech TPS - Bulkhead Mount  Independent Relays  8237-2602

Description

The ProTech® TPS (Total Protection System) is a safety system that provides specialized overspeed

protection functions plus additional programmable logic and configurable inputs and outputs to address

other safety critical functions.

The ProTech® TPS consists of three independent modules whose trip outputs are either independent or

voted in a 2-out-of-3 configuration.

The ProTech® TPS includes Alarm, Event, and Trip log functions with timestamping. Indication that a test

was active at the time of the event are provided on all logs and first-out indications are provided for Event

and Trip logs. Trip response time monitoring and logging is also built into the ProTech® TPS.

The ProTech® TPS provides various pre-defined and user-definable test features including automated

periodic tests.

There are several ways to interface with the ProTech® TPS. The front panel of allows the user to view

current values and perform certain configuration and test functions. All the features and most of the

information available from the front panel is also accessible via the Modbus® * interface. Finally, the

Programming and Configuration Tool (PCT) is software that is run on a PC to define configurable inputs

and programmable logic, download log files, and manage settings files.

This product is designed for critical applications and when installed correctly meets API-670. API-612.

API-611. and IEC61508 (SIL-3) standards.

Applications

The ProTech® TPS is designed to be applied as a safety system for any size steam, gas, or hydro

turbine, reciprocating engine, or plant process equipment. This safety PLC’s fast (12 millisecond)

response time, 0.5 to 32 000 rpm speed range, and integrated overspeed and acceleration

detection/protection functionality, make it ideal for application 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 ProTech® TPS 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 ProTech® TPS 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 ProTech® TPS 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 ProTech® TPS is designed for critical applications where

both personnel safety and unit availability (operation run time) is a concern or necessity.
