Module Type Introduction

ITM11A8XJ036645 is standard field signal acquisition card for MARK VI rack, equipped with 8 fully galvanic isolated analog input channels. It receives continuous analog signals from field sensors including PT100 temperature probes, vibration transmitters, pressure transducers and speed pickups, converts analog signals into digital data via high-precision ADC chips and transmits to main processor through VME backplane bus. Triple modular redundant TMR design allows three identical ITM11A cards to run synchronous sampling and hardware voting, single channel fault will not trigger unit shutdown. Built-in complete self-diagnosis circuit, it is standard replacement spare part for power plant turbine safety monitoring loops.
