Sincal has developed an electrical panel adaptable to all boilers that, by means of an automaton specifically designed for pressure equipment, allows to operate and obtain in a simple and intuitive way all the boiler organs.
This system allows the boiler safety chain to comply with the SIL-2 standard, being this a completely new aspect among national manufacturers of steam boilers.
The Safety Integrity Level, abbreviated SIL, ( Safety Integrity Level) is a relative level of risk reduction provided by a safety function.
The EN 61508 standard defines SIL using requirements grouped into two broad categories: hardware safety integrity and systematic safety integrity. A device or system must meet the requirements of both categories to achieve a given SIL.
The requirements for safety integrity are based on statistical analysis. To achieve a given SIL, the device must meet the targets for the maximum probability of error. The actual targets required vary depending on the probability of a claim, the complexity of the device and the types of redundancy used.
The PFD (Probability of Failure on Demand) and RRF (Risk Reduction Factor) is defined in EN 61508 for continuous operation as follows:
| SIL | PFD | PFD (current) | RRF |
| 1 | 0.00001-0.000001 | 10-5 – 10-6 | 100,000-1,000,000 |
| 2 | 0.000001-0.0000001 | 10-6 – 10-7 | 1,000,000-10,000,000 |
| 3 | 0.0000001-0.00000001 | 10-7 – 10-8 | 10,000,000-100,000,000 |
| 4 | 0.00000001-0.000000001 | 10-8 – 10-9 | 100,000,000-1,000,000,000 |
The system consists of two electronic boards and a touch screen:
Sincal 0100 relay board
The E0100 relay board, located inside the electrical panel, is designed and built for the purpose of providing physical security to a steam boiler.
For this purpose, the equipment does not use firmware or microprocessor logic, but rather all the logic developed in the device is physically implemented on the board and its design.
The power board collects various physical signals from the boiler with two main functions:
Act by providing the necessary safety signals to safeguard the integrity of the installation by providing the necessary regulatory and safety measures.
Channel the information to the controller also allowing the controller to provide additional signals to the connected elements.
Sincal 0101 controller board
The E0100 is designed and built for the purpose of monitoring and controlling a steam boiler with different configurations.
The monitoring data are obtained through digital and analog inputs, either obtained directly (own connections) or from the E0100 board.
The control is performed by acting on the E0100 board, as well as directly through the analog output integrated in the unit. The unit has different communication ports to monitor and control additional external devices.
Control supervision, monitoring and adjustment can be performed:
Touch screen
From the touch screen located on the front of the control panel, it is possible to operate the boiler and obtain real-time information on all the boiler’s control components.
The visualization is done through a diagram of the boiler, which confers a high degree of simplicity to the user.
