CS AR-01ME02 Pizzato Safety module 2NO+1NC, category 4

Why Choose the Pizzato CS AR-01ME02 Safety Module?

The Pizzato Elettrica CS AR-01ME02 is a compact safety relay module with 2 NO safety contacts and 1 NC signalling contact, designed for monitoring safety devices in industrial machinery. Part of the Pizzato CS AR Series, it provides a dedicated interface between safety inputs and machine control circuits, helping implement dependable safety functions for guards, emergency stops and other compatible safety devices.

Designed for demanding machine-safety applications, the CS AR-01ME02 can be used in safety-related control systems up to Category 4 and Performance Level PL e when the complete system is correctly designed and validated. Its positively guided relay architecture provides 2 normally open safety outputs for safety-related switching together with 1 normally closed auxiliary signalling contact.

The CS AR-01ME02 operates from a 24 V AC/DC supply and uses screw terminals for straightforward control-panel wiring. Its slim 22.5 mm housing helps conserve DIN-rail space, while selectable start/restart arrangements make the module suitable for a broad range of machinery safety circuits.

Reliable Safety Relay Monitoring for Industrial Machinery

A safety relay module evaluates signals from connected safety devices and controls redundant safety outputs according to the required machine-safety logic. In applications such as emergency-stop circuits or movable-guard monitoring, opening the safety input circuit causes the safety relay outputs to switch to their safe state so that compatible downstream contactors or control equipment can remove or prevent hazardous machine operation.

The CS AR-01ME02 provides 2 normally open safety contacts for safety-related switching and a separate normally closed auxiliary contact for signalling or status monitoring. When incorporated into a correctly designed safety circuit, its redundant architecture can support applications up to Category 4 and PL e, making it suitable for machinery requiring a high level of functional safety performance.

Typical Applications

• Emergency-stop circuit monitoring.
• Safety guard switch monitoring.
• Movable machine guard interlocking.
• Industrial machinery safety circuits.
• Packaging and production machinery.
• Machine tools and machining equipment.
• Conveyor and material handling systems.
• Automated manufacturing equipment.
• Safety contactor control and monitoring.
• Machine access and operator protection systems.
