Why Choose the Pizzato CS AM12F1MU-P8 Safety Module?
The Pizzato CS AM12F1MU-P8 is a dedicated motor standstill detection safety module designed for machine safety applications where access or other safety functions must be enabled only after hazardous motor movement has stopped. Part of the advanced Pizzato CS AM series, this sensorless module monitors residual voltage on the motor phases and provides three safety-related normally open relay contacts.
Designed for safety applications up to Category 4, PL e and SIL 3, the CS AM12F1MU-P8 provides dependable motor standstill monitoring without requiring an external speed encoder. Galvanic separation between the control and measuring circuits supports robust integration, while selectable residual-voltage sensitivity enables the module to be adapted to different motors and machine configurations.
The CS AM12F1MU-P8 operates from a 24 V DC supply and uses a 45 mm-wide housing with removable screw-terminal connectors. It is a non-programmable CS AM12 configuration, making it a practical solution for machinery requiring dedicated standstill detection and three safety relay outputs.

Reliable Motor Standstill Detection for Machine Safety
Motor standstill monitoring is used where a machine safety system must determine that hazardous motor movement has ceased before allowing an associated safety action, such as guard unlocking. The Pizzato CS AM12F1MU-P8 monitors residual voltage on the motor phases, allowing standstill to be detected without relying on a conventional shaft-mounted encoder.
The CS AM series provides galvanic separation between its control and measuring circuits and offers multiple residual-voltage sensitivity levels for adaptation to different motor characteristics. The CS AM12F1MU-P8 combines this monitoring technology with three normally open safety relay contacts, enabling straightforward integration into high-performance machine safety circuits.
Typical Applications
- Motor standstill monitoring on industrial machinery.
- Guard-locking safety systems.
- Machine access control after hazardous motion has stopped.
- Conveyors and material-handling machinery.
- Rotating industrial equipment.
- Production and processing machinery.
- Machine safety circuits requiring up to PL e / SIL 3 performance.
