Vibro-meter VMF IOC16T 16-Channel I/O Module

The Vibro-meter VMF IOC16T is a versatile 16-channel input/output module designed for the VMF series condition monitoring system. This module serves as a flexible interface between field sensors and the VMF rack, supporting a wide range of signal types for comprehensive machinery protection and condition monitoring applications.

Channel Architecture

Each of the 16 channels is independently configurable to accept various input types including voltage, current, and digital signals. The module provides integrated signal conditioning with programmable gain stages and filtering options. Input ranges are software-selectable, accommodating sensor outputs from accelerometers, velocity sensors, proximity probes, temperature transmitters, and other industrial instrumentation.

• Channel Count: 16 independently configurable channels

• Input Types: Voltage (±10 V, ±5 V), Current (4-20 mA), Digital (24 V)

• Resolution: 24-bit ADC per channel

• Sampling Rate: Up to 50 kHz per channel

• Filtering: Programmable anti-aliasing filters

• Excitation: Constant current for ICP sensors, sensor power supply

• Isolation: Channel-to-channel and channel-to-backplane

• Operating Temperature: -20°C to +65°C

Signal Processing

The IOC16T performs real-time signal processing at the module level, reducing the processing burden on the system controller. Each channel independently calculates overall vibration amplitude, displacement values, and process parameters. For vibration channels, the module supports synchronous and asynchronous data acquisition with configurable bandwidth settings. All processed data is transmitted to the system controller over the VMF backplane bus.

Diagnostics and Reliability

The module incorporates comprehensive diagnostic capabilities including sensor integrity monitoring, open-circuit detection, and short-circuit protection. Status LEDs on the front panel provide visual indication of channel activity, communication status, and fault conditions. The IOC16T supports hot-swap functionality, allowing module replacement without system interruption in redundant configurations.
