Input Channels: There are 8 input channels, which can perform speed detection simultaneously. Input Voltage Range: 5V to 24V DC. Operating Temperature: -20°C to +70°C. Storage Temperature: -40°C to +85°C. Humidity Tolerance: 5% to 95%, non-condensing. Dimensions: 155mm (height) × 100mm (width) × 20mm (depth). Weight: Approximately 500g.
Functional Features Multi-channel Detection: With 8 channels, it can collect and process signals from multiple speed sensors simultaneously, meeting the needs of monitoring the rotational speeds of multiple parts in complex equipment systems. Selectable High and Low Resolutions: It supports 16-bit low resolution and 32-bit high resolution modes, allowing for flexible selection according to actual measurement accuracy requirements. For equipment with a large range of rotational speed changes and high accuracy requirements, the high resolution mode can be selected; for scenarios with general accuracy requirements, the low resolution mode can meet the needs. Multiple Input Types: It has multiple input types, including high resolution speed value input, low resolution speed value input, open circuit input, overspeed input, etc., which can be adapted to different types of speed sensors and measurement requirements.
Working Principle: Signal Input: This module is usually connected to a speed sensor to receive signals from the sensor. The speed sensor can be of various types, such as photoelectric sensors, magnetic sensors, etc. They will generate corresponding electrical signals according to the rotation or movement of the measured object. These signals are generally frequency signals, and their frequency is proportional to the speed of the object. For example, when the motor shaft rotates, the speed sensor connected to the motor shaft will generate a frequency signal corresponding to the rotational speed of the motor and transmit it to the 1C31189G01 module. Signal Processing: After the 1C31189G01 module receives the sensor signal, it will perform a series of processing on it. There is a signal conditioning circuit inside the module, which is used to amplify, filter and other operations on the input signal to improve the quality of the signal and remove noise and interference. Then, the frequency of the signal is accurately measured through a counting circuit. For example, the number of signal pulses is counted within a certain period of time to obtain the frequency value. According to the measured frequency, the module then converts it into the corresponding speed value through an internal algorithm. Data Output and Transmission: The module outputs the processed speed data in the form of digital signals. These data can be transmitted to the upper computer or other controllers through the communication interface between the module and the Ovation system. For example, the speed data is transmitted to the PLC or DCS system for further monitoring, analysis and control. At the same time, the module may also have some status output signals, such as alarm signals. When the detected speed exceeds or is lower than the set threshold value, corresponding alarm signals will be output to notify the operator or trigger other relevant control actions.
Installation and Maintenance Installation Requirements: It is usually installed in the control cabinet of the Ovation system and needs to be installed correctly in accordance with the installation specifications of the system to ensure normal electrical connection and communication between the module and other devices. Maintenance Key Points: Regularly check the working status of the module, including whether the indicator lights are on normally and whether there are phenomena such as abnormal heating. At the same time, ensure good heat dissipation of the module and avoid dust accumulation from affecting its performance. When upgrading or maintaining the system, operations should be carried out in accordance with the relevant guidelines of Emerson to ensure the compatibility and stability of the module and the system.
