SSi-4 Plus4-Channel Sensor InterfaceBrand: INNOVATEPart Number: IM3914Description: The SSI-4 PLUS includes theSSI-4 PLUS, Serial Program Cable, Molex to Molex Patch Cable (to daisy chain with other MTS compatible devices),and manual. P/N 3914 TheSSI-4 PLUS will allow the capture of data from 4 external sensors. These sensors can be frequencies such as engine RPM and speed sensors or 0-5V references like MAP sensors and pressure transducers. The SSI-4 PLUS may be used as a stand-alone system or integrated with other Innovate Motorsports MTSproducts to create a log chain. Simple sensor device that adds 4-inputs to an MTS Log Chain Channel 1 and 2 inputs can be configured for RPM, Speed (VSS), Frequency, and 0-5 volt. In addition to the above, the channel 2 inputcan be used for duty cycle or dwell. Channel 3 and 4inputs can be used for 0-5 volt 5 volt output to power external sensors
