Meggitt VM600 Hardware Manual

9 - 24 VM600 MPS hardware manual (standard version) MAMPS-HW/E
Edition 17 - February 2018
Connecting speed sensors
CONFIGURATION OF MPC4 / IOC4T CARDS
9.3.2.2 Current-modulated signal
Applies to the following transducers or transducer and signal conditioner systems:
• TQ4xx + IQS45x.
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- The sensor power supply is always set to 27.2 V.
NOTE: For speed/phase reference input channels, it can be more difficult to achieve the
minimum input voltage required when current is selected as the signal
transmission mode. Therefore, the 200  current-to-voltage conversion resistor
used by the MPC4 card for current-modulated input signals should be used in any
system design calculations in order to ensure reliable detection.
