High-quality, high-reliability capacitive-coupling adaptor for the MPC4/IOC4T card pairs used by VM600 rack-based machinery monitoring systems. The IOC4T capacitive-coupling adaptor supports 4 channels, which are buffered "raw" transducer output signals. An IOC4T capacitive-coupling adaptor is installed into a screw-terminal socket (J3) of an IOC4T card in the rear of a VM600 ABE04x rack.Features4 individually configurable channels for use with IOC4T buffered (raw) transducer outputsAC couples a channel's buffered (raw) transducer output signal and removes the DC component1 ?F series capacitor or straight-through connection per channelReduces external circuitry and wiring when the buffered (raw) transducer outputs of an IOC4T card are connected to test and measurement equipment
