Connecting vibration and pressure sensors
CONFIGURATION OF MPC4 / IOC4T CARDS
9.2.2.2 Current-modulated signal
Applies to the following transducers or transducer and signal conditioner systems:
• CAxxx + IPC70x (2-wire, current modulation)
•CE1xx
•CE3xx
• CPxxx + IPC70x (2-wire, current modulation, Note: This setup is not recommended)
• CV210 + IVC632 (PS = −27.2 V, HI = COM)
• SE120
• TQ4xx + IQS45x (PS = −27.2 V, HI = COM).
Notes
1- Switch Sw1 is closed to allow current-modulated signals to be processed.
For non-vibro-meter devices, the Signal Transmission Mode field has to be set to the
Current option.
2- Switch Sw2 is set to position 1 to connect the IOC4T card's sensor power supply to the
PS terminal.
For non-vibro-meter devices, the Sensor Power Supply field has to be set to the
appropriate voltage (+27 VDC, −27 VDC or +15 VDC).
3- The required power supply for the IPC70x is +27.2 V.
