Vibro-Meter VM600 MPC4 machinery protection card

Dynamic signal inputs 

Number of inputs : 

4 per MPC4 card 

DC range : 0 to +20 V or 0 to −20 V 

AC range : ±10 V max. 

Common mode voltage range : −50 to +50 V 

CMRR : >60 dB at 50 Hz 

Crosstalk : −72 dB 

Input impedance : 200 kΩ 

Current input range 

• DC signals : 0 to 25 mA 

• AC signals : ±8 mA max. Analog frequency range : DC to 60 kHz (−3 dB). Note: Applicable when dynamic signal outputs are shared using the Raw bus (VM600 rack). Dynamic signal outputs can be shared with XMx16/XIO16T card pairs but cannot be shared with other MPC4/IOC4T card pairs.

Analog AC frequency range

• Without integration : 0.1 Hz to 10 kHz 

• With integration : 2.5 Hz to 10 kHz 

Current measuring resistor : 324.5 Ω

Buffered dynamic signal outputs

The buffered “raw” dynamic signal outputs are available on the front-panel BNC connectors (MPC4 card) and the screw-terminal connectors (IOC4T card). 

Output impedance : 50 Ω 

Analog frequency range :

DC to 10 kHz (−0.1 dB with a load >1 MΩ). 

DC to 10 kHz (−0.2 dB with a load >200 kΩ). 

DC to 40 kHz (−3 dB).

Analog (DC) outputs and discrete outputs

Analog (DC) outputs and discrete outputs (relays) are available on the associated IOC4T card. Refer to the IOC4T input/output card data sheet for further information.
