ProTech TPS – Bulkhead Mount Independent Relays 8237-2602
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.
