Product Introduction

characteristic
Dual channel design: It can simultaneously monitor the speed, zero speed, and key phase pulse signals of two shafts, improving monitoring accuracy and reliability. The two channels can be used independently or in combination.
Can be replaced during operation: It can be replaced during equipment operation without affecting the overall system operation, improving maintenance convenience and system availability.
Single use and redundant power input: It can be used separately and also supports redundant power input, enhancing the stability and reliability of the equipment, ensuring that it can still work normally in case of power supply problems.
Extended self checking function: Equipped with built-in sensor self checking function, it can monitor the working status of sensors and modules in real time, detect faults in a timely manner, and issue alarms or take corresponding measures.
Password protection operation level: There is a password protection operation level to ensure that only authorized personnel can set parameters and operate the device, improving the security and stability of the system.
Multiple sensors applicable: suitable for eddy current sensor PR642./ Series with preamplifier CON0X1, or PR9376/ Sensors with strong compatibility can meet the needs of different application scenarios.
Electrical isolation current output: The output signal adopts electrical isolation technology, which can effectively avoid signal interference and improve measurement accuracy and stability.
Communication function: Equipped with RS232/485 ports for on-site configuration and communication, it can easily read measurement values for users to set parameters and monitor data.

technical specifications
input
Signal input: There are two independent sensor signal inputs, SENS 1H (z8)/SENS 1L (z10) and SENS 2H (d8)/SENS 2L (d10), which can be adapted to eddy current sensors or Hall effect sensors.
Voltage range: The input voltage range is 0... -27.3V DC, and the module provides two channels of -26.75V DC power supply for the sensor.
output
TTL pulse output: There are two TTL pulse outputs, one for each channel, with a voltage of 0...+5V. The width and frequency of the pulses are related to the sensor signal.
Key phase signal output: Two key phase signal outputs, one for each channel, with a maximum output voltage of 24V, can be used to determine the position of the axis or control the sampling and control of other modules.
Eigenvalue output: Two current outputs representing speed, 0/4... 20mA, one for each channel, used to convert the speed signal into a standard current signal output.

Limit monitoring
Alarm output: Provides 4 independent alarm outputs, with different function options in dual channel mode and redundant mode. It can be configured as alarm types such as "rising over limit", "falling over limit", "turning", "differential" or "rotation direction" according to user requirements.
Alarm switch working mode: The external input d24/z24 can choose the alarm switch working mode, which can be set to normally open or normally closed.

application
Power industry: used to monitor the speed of equipment such as turbines and generators, ensuring the safety and stability of power production.
Petrochemical industry: It can monitor the speed of equipment such as compressors and pumps to prevent equipment failures and shutdowns caused by abnormal speed, ensuring the smooth progress of the production process.
Steel metallurgy industry: suitable for monitoring the speed of equipment such as rolling mills and fans, which helps to improve production efficiency and product quality.
Other industrial applications, such as fans, centrifuges, gearboxes, and other equipment that require speed monitoring, can be monitored using EPRO MMS6312 to ensure stable operation of the equipment.
