The Phares ZS11 Motion Detector Module is particularly useful in applications where more than one sensor is used at a single point of measure to determine varying speeds. The ZS11 contains three relay outputs which operate via a single sensor input signal. Each relay output is adjustable, providing three independent speed level settings in one module.

The ZS11 is useful in applications where environmental conditions, such as high temperature, prohibit the use of certain electronics. In these cases, the sensor is installed in the prohibitive area and wired to the Phares ZS11 Motion Detector Module which is located out of the prohibitive area. Use for applications in locations classified as hazardous only when properly coupled with UL approved intrinsically safe barriers and sensors.

The ZS11 can be integrated with existing industrial control systems or used as a stand-alone unit. It is DIN rail mountable for easy installation.

 

Description

The Phares Electronics Model ZS11 Motion Detection System consists of the Phares ZS11 Motion Detector Module, Sensor and Sensor Target, all sold separately. The Sensor Target can be a bolt head, geartooth, key stock, magnet, reflector, or other target depending upon type of Sensor used.

The Sensor Target is installed/located at the point of measure. Motion is detected when the rotating Target triggers the Sensor. When motion is either detected or reaches setpoint, the relay outputs change state. They remain in this state until either under speed or zero speed condition occurs, depending upon the application.

The Phares ZS11 Motion Detector Module supplies 12 VDC to an external Sensor. The Sensor must be 3 wire, sourcing (PNP) or sinking (NPN) signal. Sensor input signal is configured via two position selector switch located at the top right of the terminal strip.

The Phares ZS11 Motion Detector Module uses frequency input from various types of sensors to determine the presence of motion or the lack thereof. Use the ZS11 for over speed, under speed, and zero speed applications.

Sensor types compatible with the Phares ZS11:

Sensors and Targets

The Phares ZS11 Zero Speed Switch System requires a sensor and sensor target suitable for measuring speed. Sensor and sensor targets are sold separately.

Suitable targets are:
Magnetic Disk
• Split Coupling
• Geartooth wheel
• Bolt head or key stock with high ferrous (iron) content already on machine.

 

Sensors

Phares Electronics Digital Output Hall Effect Sensors and Geartooth Sensors are simple on/off non-contact switching devices. Digital output signal is clean, fast and switched without bounce. They are magnetically activated switches that detect the presence and motion of the shaft speed monitoring target.

Phares Electronics’ Hall Effect Sensors and Geartooth Sensors are produced in a variety of sizes. Contact us for technical support and assistance with choosing a sensor and sensor target for your application.
