TRICONEX 4119A Redundant power modules

The TRICONEX 4119A is a Safety Instrumentation System (SIS) redundant power module manufactured by TRICONEX, a member of the Trident family of SIS redundant power modules.

The TRICONEX 4119A is primarily used to provide redundant power to SIS controllers and I/O sites to meet the high reliability requirements of power supplies for industrial automation systems. It uses a redundant design, when the main power supply fails, the backup power can quickly take over, ensuring uninterrupted operation of the system, thus avoiding production interruptions and possible safety incidents. In addition, the TRICONEX 4119A has a variety of features to meet the needs of different applications.

Redundant design: The TRICONEX 4119A features a redundant design that includes redundant input and redundant output channels to ensure that the system will still function properly if one channel fails.
Real-time acquisition and control: The module can collect external signals and control external equipment in real time, and accurately control the operating state of industrial processes according to the control logic and algorithm of the system.
Fault detection and recovery: The module usually has a fault detection function, which can detect the fault of the input/output channel, and timely alarm or take appropriate measures for fault recovery to ensure the stable operation of the system.
Modular design: The TRICONEX 4119A features a modular design that makes installation and maintenance easier.
Communication interface: The module usually has an interface to communicate with the Triconex security system in order to exchange data and communicate with other modules to achieve system integration and collaborative work.
Input voltage: 120VAC or 240VAC; Output voltage: 24VDC; Output current: 10A; Redundancy mode: 1+1 or N+1.

TRICONEX 4119A is widely used in petrochemical, power, manufacturing and other industries. In these fields, it plays a vital role in ensuring the continuous operation and safety performance of industrial automation systems. By using the TRICONEX 4119A, companies can increase productivity, reduce operating costs, and improve their overall competitiveness.
In summary, the TRICONEX 4119A is a powerful and reliable safety instrumentation system redundant power module for continuous operation and safety performance of industrial automation systems.

TMR Digital Input Modules Each TMR Digital Input (DI) module has three isolated input channels which independently process all data input to the module. A microprocessor on each channel scans each input point, compiles data, and transmits it to the Main Processors upon demand. Then input data is voted at the Main Proces￾sors just prior to processing to ensure the highest integrity. All critical signal paths are 100 percent triplicated for guaranteed safety and maximum avail￾ability. Each channel conditions signals independently and provides optical isolation between the field and the Tricon. All TMR Digital Input Modules sustain complete, ongoing diagnostics for each channel. Failure of any diagnostic on any channel activates the module Fault indicator, which in turn activates the chassis alarm signal. The module Fault indicator points to a channel fault, not a module failure. The module is guaran￾teed to operate properly in the presence of a single fault and may continue to operate properly with certain kinds of multiple faults. Models 3502E, 3503E, and 3505E can self-test to detect stuck-On conditions where the circuitry cannot tell whether a point has gone to the Off state. Since most safety systems are set up with a de-energize-to-trip capability, the ability to detect Off points is an impor￾tant feature. To test for stuck-On inputs, a switch within the input circuitry is closed to allow a zero input (Off) to be read by the optical isolation circuitry. The last data reading is frozen in the I/O communication processor while the test is running. All TMR Digital Input Modules support hot-spare capability, and require a separate external termination panel (ETP) with a cable interface to the Tricon backplane. Each module is mechanically keyed to prevent improper installation in a configured chassis.
