TRICONEX 2750
Product Name
TRICONEX 2750 Safety-Grade Digital Output Module(Positioning: A critical safety output unit in TRICONEX’s Tricon safety instrumented system (SIS), compliant with IEC 61508 SIL 3 and TÜV Rheinland certifications. Core function: Transmitting safety-critical control signals (e.g., emergency shutdown, valve actuation) from the Tricon controller to field executive devices (e.g., solenoid valves, contactors), ensuring rapid and reliable execution of safety logic to protect personnel, equipment, and the environment in high-risk industrial processes.)
2. Product Description
2.1 Core Positioning and Technical Advantages
As a key component of TRICONEX’s safety control ecosystem, the 2750 module integrates SIL 3-certified safety architecture, multi-channel isolated output, and industrial ruggedness to address three core challenges in safety-critical applications:
- Inability of standard digital output modules to meet strict safety requirements (e.g., fault tolerance, failure rate limits) in high-risk industries, leading to potential safety incidents from failed control signal transmission;
- Signal interference and cross-talk between output channels in harsh industrial environments (e.g., electromagnetic noise from motors, voltage surges), causing false actuation or failure of field devices;
- Poor environmental adaptability (e.g., high temperature, humidity, vibration) leading to module failures and SIS downtime, compromising process safety and compliance with industry regulations.
2.2 Key Functions and Features
-
SIL 3-Certified Safety Performance: Complies with IEC 61508 SIL 3 and IEC 61511 safety standards, with a safe failure fraction (SFF) ≥90% and a hardware fault tolerance (HFT) of 1. It adopts a redundant circuit design for critical components (e.g., power drivers, output switches) to eliminate single-point failures. The module supports online self-testing (IST) and periodic proof testing, with a proof test interval (PTI) of up to 10 years, ensuring long-term compliance with safety requirements for processes such as oil refining reactors, chemical storage tanks, and power plant boilers.
-
16-Channel Isolated Digital Output: Features 16 independent digital output channels, each supporting either relay output (for high-power devices) or solid-state output (fo
