8237-1604 ProTechTPS is a safety PLC

Product Description

Programming

• The ProTechTPS functions as a safety PLC, as it accepts 10 discrete or analog inputs per module (30 total), and allows users to create custom safety/protection programs to safely protect site personnel and equipment. Programmers are able to utilize typical logic and testing sequence routines to create their application-specific safety logic and tests.

On-Line Testing

• Each ProTechTPS module can be tested manually from the module’s front panel, Modbus communications port, or automatically via its auto-test routine function. The ProTechTPS allows users to configure overspeed or custom-programmed tests to be performed manually or automatically on a periodic basis. With these test routines, each module (A, B, C) is tested one at a time, and either a successful test result is logged or, upon sensing a fault, the routine is halted and the sensed fault indicated/alarmed.

On-Line Repair

• The ProTechTPS’s triple modular design allows users to easily replace one of its modules (A, B, C) while the monitored equipment/turbine is on-line and operating normally. Ease of replacement is enhanced by the unit’s backplane plug-and-operate structure, and its module-to-module learning function.

Trip, Alarm, & Overspeed Logs

• The ProTechTPS log function logs (saves to memory) all trips, alarms, trip valve response times, and overspeed events. The trip log function uses a scrolling buffer and records the last 50 sensed trip or alarm events and the last 20 overspeed events to memory, with associated times. Each log file can be viewed from the unit’s front panel, or downloaded to a computer via the ProTechTPS service tool program. Each module utilizes nonvolatile memory to ensure that all logged events are saved, even on loss of power.

Real Time Clock

• Each ProTechTPS module utilizes a real-time-clock to ensure accurate time logging. A special time averaging function is utilized between modules to ensure module-to-module clock synchronization. Alternatively one of the ProTechTPS’s inputs can be configured to accept a discrete clock synchronization input signal from a plant DCS or other time synch device.
