Safety relay for hazardous process environments

With the PSR-MC35-EXI safety relay, Phoenix Contact introduces a solution for functional safety in hazardous industrial environments. The device is designed for use in Zone 2 and is certified according to IECEx and ATEX, meeting international requirements for explosion protection. Typical application areas include process and chemical industries, particularly where gas or dust atmospheres are present.

Reliable operation under demanding conditions
The safety relay is engineered for reliable performance in harsh environments. A coated printed circuit board protects the electronics against corrosion. An extended operating temperature range up to +60 °C enables use in applications with elevated thermal demands.

A key feature is the ability to connect equipment that can be installed in Zone 0 (gas) and Zone 20 (dust). This allows the relay to be integrated into safety-related systems covering multiple explosion zones within a plant.

Compact design and flexible installation
With a housing width of 17.5 mm, the device supports space-saving installation in control cabinets. The compact design is based on proven relay technology and enables high functional density in safety control systems.

The product is available with either screw or push-in connections, allowing adaptation to different wiring requirements.

Safety ratings and application scope
The PSR-MC35-EXI meets safety requirements up to SIL 3 in accordance with IEC 61508 and Performance Level e (PL e) according to ISO 13849. This makes it suitable for applications with high functional safety requirements, such as chemical processing plants, energy generation facilities, and industrial process systems.

With the PSR-MC35-EXI, Phoenix Contact addresses the need for compact, certified safety solutions in hazardous environments, supporting the implementation of safety-related automation systems in industrial operations.
