Certified Safety and Proven Reliability
The QUADLOG safety PLC provides cost-effective safety and availability along with seamless integration with the APACS+TM process control system. QUADLOG is a program-mable electronic system (PES) for potentially dangerous applications, such as emergency shutdown, burner management, and fire and gas detection.
QUADLOG delivers a safer, more cost-effective solution than traditional programmable technologies. Unlike conventional PLCs, which require additional hardware and engineering for adequate protection, QUADLOG's built-in safety features provide pre-configured and pre-tested safety mechanisms that have all been independently certified. In fact, QUADLOG's safety certification equals that of triple modular redundant (TMR) systems, but for less cost, lower complexity, and with greater system reliability.
With its rugged hardware, extensive diagnostics, as well as other features, QUADLOG has been evaluated and certified by a variety of third-party organizations. QUADLOG carries the following approvals:
- TUV approval to level AK6
- Approved to IEC 61 508 SIL 3
- CE mark
- FM approval for Class I, Div. 2 hazardous locations
- CSA approval for Class I, Div. 2 hazardous locations
- ABS type approval
- UL 508
The above approvals enable the QUADLOG safety PLC to meet rigorous industry standards and government regulations.
This unique, proven approach to safety and reliability has led many companies to choose QUADLOG for their critical process control applications.
