Safety timer modules

CS FS series safety timer modules are designed to guarantee a safety circuit only opens after a set delay, or that a guard remains locked until dangerous machine parts have come to a complete stop.

Functioning of CS FS safety timer modules

Pizzato CS FS series safety modules are electromechanical devices designed to implement timed safety management with preset functions, guaranteeing reliable control of activation and deactivation sequences in industrial systems. They stand out for simplicity of application and offer a range of timer functions. These devices are suitable for use with automatic machinery, robotic systems, handling systems and production lines with fixed timing requirements.

Applications of the CS FS series

OFFdelay safety stop

Enables progressive stop of mechanical components with inertia or the safe dissipation of residual energy.

Timed start-up sequence

Guarantees safe and sequenced activation of actuators and protection devices, avoiding overloads or untimely start-up.

Delayed control of safety contactors or solenoid valves

Enables reliable, time-controlled management of the power circuit.

Synchronisation of additional functions

Coordination of functions such as signalling lights, extractor fans and auxiliary systems.

Safety circuits with mandatory sequences

When the machine logic requires a delay between the enabling of various subsystems.

Safety levels and timer functions

High level of safety

International standards

Performance level up to PL e in accordance with EN ISO 13849-1, Safety Integrity Level SIL 2 to SIL 3 in accordance with EN IEC 62061/EN IEC 61508 and Safety Categories 3 to 4 in accordance with EN ISO 13849-1.

Different timer functions

Preset timers

OFFdelay: keeps safety outputs active for a set time after loss of consent.
ONdelay: enables outputs after a preset time interval.

Start-up modes

Automatic – Manual

A version is available with automatic start-up following input-signal consistency and manual start-up via an external NO contact.

45 mm

Width of 45°mm

All modules are designed with a width of 45°mm for easy installation even in compact switching cabinets.
