In the Schneider Electric stand at Hannover Messe was a new programmable safety controller based on the Telemecanique brand Modicon Quantum PLC, Schneider’s top-of-the-line platform that is aimed at process control applications.

The bright-red safety PLC is certified according to the IEC 61508 standard by TÜV Rheinland Group for applications that require a Safety Integrity Level up to SIL2.

Based on standard Quantum architecture, it achieves SIL2 certification as a result of the integrated design in the PLC that allows standard wiring, cabling and programming along with extensive internal diagnostics at the I/O levels and CPU level. No additional hardware (such as voter and splitter hardware) and no additional wiring or logic are needed. The new offer consists of two CPUs, each containing two microprocessors from different manufacturers, and three I/O modules. Self-testing diagnostics means redundant wiring and additional modules are not necessary.

Schneider’s aim is for applications such as emergency systems, protection of steam boilers, fire and gas detectors, and burner controls.
