Why Choose the Pizzato CS AM21P1MU Motor Speed Safety Module?
The Pizzato CS AM21P1MU is a programmable motor speed and direction-of-rotation safety module designed for machinery where safe operation depends on monitoring motor movement. Part of the Pizzato CS AM series, it combines motor speed measurement, rotation-direction detection and 2 OSSD safety outputs in a compact 22.5 mm-wide housing.
Unlike the CS AM1x models dedicated primarily to motor standstill detection, the CS AM21 family is specifically designed to monitor motor rotation speed and direction of rotation. It can operate using sensorless monitoring or with a proximity sensor, providing flexibility for different motor and machine configurations.
The CS AM21P1MU operates from a 24 V DC supply and is programmable through its USB port using Pizzato's CS AM Configurator software. Safety performance up to Category 4, PL e and SIL 3 makes it suitable for demanding machine-safety systems requiring reliable speed supervision and direction monitoring.

Programmable Safety Monitoring of Motor Speed and Rotation Direction
The Pizzato CS AM21P1MU is designed for applications where the machine safety system needs to supervise motor rotation rather than simply determine whether a motor has stopped. The module can measure motor speed and detect the direction of rotation, enabling safety functions to respond to defined operating conditions.
The programmable CS AM••P platform uses Pizzato's CS AM Configurator software to define operating parameters. The software provides project, setting and monitoring functions, including the ability to configure speed thresholds and direction-of-rotation detection and to monitor module status during commissioning and diagnostics.
Typical Applications
- Safety-related motor speed monitoring.
- Direction-of-rotation supervision.
- Rotating industrial machinery.
- Conveyors and material-handling systems.
- Machine tools and production equipment.
- Packaging and processing machinery.
- Applications requiring safety-rated minimum or maximum speed supervision.
- Industrial safety systems requiring up to PL e / SIL 3 performance.
