ADDITIONAL SPECIFICATIONS – FOR “STANDARD” AND “SEPARATE CIRCUITS” MPC4 CARDS ONLY Speed / phase reference inputs Number of inputs : 2 per MPC4 card Triggering method : Crossing of thresholds on rising/falling edge of signal Triggering thresholds : Rising = 2/3 of peak-peak value, falling = 1/3 of peak-peak value Tachometer range : 0.016 Hz to 50 kHz on input. 0.016 Hz to 1092 Hz (1 to 65535 RPM) after division by the wheel teeth number. Speed resolution : 0.001 Hz (internal) Input voltage range : 0.4 to 500 Vpp in the range 0.3 Hz to 10 kHz. 2.0 to 500 Vpp in the range 10 kHz to 50 kHz. Minimum input voltage for reliable detection • Square-wave input signal : 0.8 Vpp (0.016 Hz to 10 kHz). 2.0 Vpp (10 kHz to 50 kHz). • Sinusoidal input signal : 10 Vpp (0.016 Hz to 1 Hz). 2.0 Vpp (1 Hz to 10 Hz). 0.8 Vpp (10 Hz to 10 kHz). 2.0 Vpp (10 kHz to 50 kHz). Range of DC component : −20 to +20 V 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 Ω 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 help ensure reliable detection. Buffered speed / phase reference outputs The buffered “raw” speed/phase reference outputs are available on the front-panel BNC connectors (MPC4 card). BNC outputs : TTL compatible Outputs to IOC4T and Tacho bus (VM600 rack) : TTL compatible Speed resolution : 1 RPM (external) Processing functions Narrow-band (tracking) processing Constant Q filter : Q = 28 Frequency range : 0.15 Hz to 10 kHz Max. frequency ratio in selected band : fupper / flower = 25 Rate of change of speed : 450 Hz/sec. (in band 25 to 500 Hz) Order extraction : 1/3 X, 1/2 X, 1X, 2X, 3X, 4X Phase error : <±6° max. <±1° typ. (with order = 1X). Amplitude accuracy : ±1.2% Linearity error : <±1% Note: MPC4 card speed/phase reference (tachometer) channels and any associated processing, and narrowband (tracking) processing are not valid for use in safety-related system applications. That is, these MPC4 card processing modes (signal processing functions) are not included in the SIL 1 certification for the card and should not be configured and used in functional safety contexts. For further information, refer to the VM600 functional safety manual.

MPC4 Different versions of the VM600 machinery protection card:

– Standard 200-510-SSS-1Hh

– Separate circuits 200-510-SSS-2Hh

– SIL safety (MPC4SIL) 200-510-SSS-3Hh

Notes

Versions of the MPC4 card are available with a conformal coating (“varnish”) applied to the circuitry of the card for additional 

environmental protection against chemicals, dust, moisture and temperature extremes.

In 2017, the MPC4 / IOC4T machinery protection card pairs were improved to (1) be RoHS compliant and (2) provide a reduced 

buffered dynamic signal output impedance, which required a redesign of the underlying buffered “raw” dynamic signal output 

circuitry. Accordingly, the different versions of the MPC4/IOC4T machinery protection card pairs in use are:

• Later versions of the MPC4 (PNRs 200-510-SSS-115, 200-510-SSS-214 and 200-510-SSS-313 or later) and

IOC4T (PNR 200-560-000-114 and 200-560-000-212 or later), which are RoHS compliant and have an output impedance of 50 Ω.

• Earlier versions of the IOC4T (PNRs 200-510-SSS-114, 200-510-SSS-213 and 200-510-SSS-312 or earlier) and

IOC4T (PNR 200-560-000-113 and 200-560-000-211 or earlier), which are not RoHS compliant and have an output impedance of 

2000 Ω.

“SSS” represents the firmware (embedded software) version and “Hh” the hardware version. “H” increments are for major 

modifications that can affect product interchangeability. “h” increments are for minor modifications that have no effect on
