Vibro-Meter ® VM600 IOC4T input/output card

cards using the VM600 rack’s Raw bus or Open Collector (OC) bus.

For IOC4T card relay features, see Relay characteristics on page 4.

For further information on RLC16 or IRC4 relay cards, refer to the 

corresponding data sheet.

Note: In a VM600 rack (ABE4x), the Open Collector (OC) bus and/or Raw bus can be used to connect up to 

32 outputs from an MPC4/IOC4T card pair to RLC16 relay cards or IRC4 intelligent relay cards in the same rack, 

if additional relays are required.

Analog (DC) outputs

Number of outputs : 4 per IOC4T card (one per MPC4 dynamic signal channel)

Signal range : Current output (4 to 20 mA) or voltage output (0 to 10 V), 

individually selectable by a jumper on the IOC4T for each output.

Note: For current outputs, the analog output is actually driven in a 

slightly wider 2 to 23 mA range, proportional to the input signal.

Accuracy : ≤±1.5%

Linearity error : ≤±0.5%

Admissible load on output : >100 kΩ for voltage output.

<325 Ω for current output.

ORDERING INFORMATION

To order please specify

Type Designation Ordering number (PNR)

IOC4T Different versions of the input/output card (for the MPC4):

– Standard 200-560-000-1Hh

– Separate circuits 200-560-000-2Hh

Notes

Versions of the IOC4T 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
