I. Core Functions
(1) Accurate Signal Transmission and Preprocessing
Multi-channel data access: The IOC4T module is equipped with abundant input channels. Specifically, it supports 4 dynamic channels and 2 speed (tachometer) channels. Each channel can be independently configured and can connect multiple vibration sensors, speed sensors and other devices at the same time. In the monitoring scenario of large motor units, vibration sensors at parts such as motor bearing housings and shaft extensions, as well as motor speed sensors can be connected through different channels to comprehensively collect key data of equipment operation, providing detailed basis for subsequent state analysis.
Signal conditioning and transmission: For each dynamic channel and speed channel, the module has a differential signal input function, which can effectively suppress common-mode interference, ensuring that weak signals collected by sensors can be accurately transmitted to subsequent processing units in complex electromagnetic environments. At the same time, it also provides stable power output for sensors to ensure their normal operation. For example, in the monitoring of rolling mills in steel plants, even if there are a large number of strong electromagnetic interference sources on site, the IOC4T module can reliably obtain vibration and speed signals of equipment such as rolls and motors. In addition, each dynamic channel is also equipped with a differential buffered (original) sensor output, facilitating further analysis or backup of the original signal.
Signal conversion and output: The module integrates advanced signal conversion circuits. For dynamic signals, with the help of four on-board digital-to-analog converters (DACs), it can provide calibrated 0 to 10V voltage signal output; in addition, through four on-board voltage-current converters, the signal can be converted into 4 to 20mA current signal output (flexibly selectable through jumpers). This diversified form of signal output can adapt to different types of control systems and data acquisition equipment, greatly improving the compatibility and flexibility of the system.
(2) Equipment Condition Monitoring and Alarm
Local relay control: The IOC4T module is equipped with four local relays. Under the precise control of software, these relays can be associated with any specific alarm signal. In typical applications, they can be used to indicate faults in the MPC4 module or respond to problems detected by common alarms (such as sensor normal, early warning and danger signals). For example, when the monitoring system detects that the vibration amplitude of the equipment exceeds the normal range and reaches the early warning threshold, the corresponding relay can act quickly, triggering an acousto-optic alarm device by controlling the external circuit, and timely reminding operators to pay attention to the equipment status.
Digital signal transmission and expansion: The module can transmit 32 digital signals representing alarm status to the rack backplane. These signals can be utilized by optional RLC 16 relay cards and/or IRC 4 intelligent relay cards installed on the rack (selected through jumpers), thereby realizing further expansion and processing of alarm signals. In large automated production lines, equipment alarm information can be quickly transmitted to the central control system in this way, facilitating centralized management and unified scheduling, and timely taking corresponding measures to deal with equipment failures, reducing production losses.
(3) Efficient System Communication and Integration
Master-slave mode communication: The IOC4T module works in slave mode and communicates with the MPC4 module at high speed and stably through connector P2 using the industry-standard Industry Pack (IP) interface. In the VM600 system, they work closely together. The IOC4T is responsible for front-end signal collection, preprocessing and output, while the MPC4 focuses on in-depth analysis and processing of these signals. They cooperate with each other to ensure the efficient operation of the entire system.
Standardized interface design: Its front panel (i.e., the rear of the VM600 rack) is equipped with terminal connectors for connecting transmission cables from the measurement chain (sensors and/or signal conditioners). At the same time, these screw terminal connectors are also used for input and output of all signals with any external control system. This standardized interface design enables the IOC4T module to be easily integrated into various industrial automation systems. Whether it is a new monitoring project or the upgrading and transformation of an existing system, it can achieve rapid integration, reducing the cost of system construction and debugging.
