The Vibro-Meter IOC4T is an input/output card of the VM600 series, manufactured by Meggitt PLC under the Vibro-Meter brand. It serves as a signal interface for the MPC4 machinery protection card, mainly used for condition monitoring and predictive maintenance of rotating machinery. The following is the detailed information:
- Manufacturer: Meggitt PLC (Vibro-Meter brand)
- Product Series: VM600 Series
- Product Type: Input/Output Card
- Function: Expands the I/O capabilities of the Vibro-Meter VM600 DCS PLC system, enabling connection to additional sensors and actuators
- Inputs: 4 dynamic signal inputs for receiving raw vibration signals from sensors and 2 tachometer (speed) inputs for measuring the rotational speed of machinery.
- Outputs: Four on-board digital-to-analog converters (DACs) provide calibrated signal outputs in the 0 - 10V range. Four on-board voltage-to-current converters provide current output signals in the 4 - 20 mA range (jumper selectable).
- Connectors: All input/output connections are made using screw terminal connectors, with a total of 48 terminals, which is convenient for wiring and maintenance.
- Relays: Contains 4 relays that can be used for alarm signals under software control, enabling timely fault indication.
- Programmable Outputs: 32 fully-programmable open-collector outputs (jumper selectable) are connected to IRC4 and RLC16 relay cards, providing flexible control options.
- Power Supply: Some sources indicate 24 VDC, while others mention 100 - 240 VAC, 50/60 Hz. It is recommended to refer to the official documentation for the accurate value.
- Operating Temperature: -20°C to +70°C (-4°F to +158°F).
- Dimensions: Approximately 19-inch rack-mountable, with an estimated size of 300 mm x 150 mm x 200 mm, and a weight of about 2.8 kg to 4 kg.
- The IOC4T is part of the VM600 system, and the VM600 system is reported to have communication interfaces such as RS232, RS485, USB, and Ethernet. However, the specific communication interface of the IOC4T itself may be mainly through the connection with the MPC4 card and the backplane of the VM600 rack, and the detailed communication protocol and interface type for external communication may need to be determined according to the overall system configuration.
- The IOC4T is mainly used in industrial automation and process control systems, especially for the condition monitoring of rotating machinery in industries such as power generation, petrochemicals, and manufacturing. It can provide real-time vibration analysis, frequency spectrum, and trend monitoring to help detect potential faults and equipment failures, so as to realize predictive maintenance and reduce downtime.
