Working Principle Vibration or displacement signal from field transducer enters IOC4T card front terminals. The signal conditioning circuit amplifies, filters and converts raw signal, then sends processed signal to MPC4 protection card via rack bus. The MPC4 calculates vibration magnitude and compares with alarm threshold. IOC4T outputs buffered analog signal and relay alarm status according to MPC4 command. Channel diagnostic circuit monitors sensor loop impedance and triggers fault indication when wiring or sensor failure occurs.
Installation Requirements
- Insert IOC4T card into designated slot of Vibro-Meter VM600 rack.
- Connect field sensor cable to front removable terminal block.
- Use shielded twisted pair cable for vibration transducer wiring.
- Separate sensor signal cable from high power motor cables.
- Complete protective earth connection for VM600 rack.
- Configure sensor type and measurement range in configuration software.
- Simulate sensor fault to test channel diagnostic function after wiring.
Usage Notes
- Do not connect voltage exceeding sensor specification to input terminals.
- Keep cabinet environment free of oil mist and conductive dust.
- Backup project configuration before card replacement.
- Disconnect rack power before extracting or inserting card.
- Use anti-static wristband when handling spare card.
- Replace card immediately when permanent signal conditioning or channel fault occurs.
