Connecting vibration and pressure sensors
CONFIGURATION OF MPC4 / IOC4T CARDS
9.2.2 Connection diagrams for hardware powered by IOC4T / MPC4
9.2.2.1 Voltage-modulated signal
Applies to the following transducers or transducer and signal conditioner systems:
• CV210 + IVC632
• TQ4xx + IQS45x
• CAxxx + IPC70x (3-wire, voltage modulation).
Notes
1- Switch Sw1 is open to allow voltage-modulated signals to be processed.
For non-vibro-meter devices, the Signal Transmission Mode field has to be set to the
Voltage 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 powered option (+27 VDC, −27 VDC or +15 VDC).
3- The required power supply for the IPC70x is +27.2 V.
