10. t maintaining metal to metal contact between the thermistor and the Terminal Block contact ac is For a Box style Terminal Block maintain pressure while screwing down the contact Isolated Input Groups This module provides two isolated groups of four input channels each This allows fast inputs and slower or highly filtered inputs to be connected to the same module without adversely affecting the update rate of the fast inputs To take advantage of this feature up to four inputs requiring fast response should be placed together in one isolated group while slower inputs should be connected to the other isolated group For example voltage and current inputs with higher frequency input filter settings should be grouped together on one of the isolated groups while thermocouple RTD resistance or voltage current inputs with low frequency input filter settings should be grouped together on the other isolated group Each isolated group provides a CJC input The CJC input is considered a slow response input and will reduce the update rate for the associated channel group when enabled Resolution and Update Time The actual resolution and update time for each input depend on the channel s configured Range Type and A D Filter Frequency as described in the RX3i System User s Manual GFK 2314 At higher Filter Frequencies channel update time increases while input resolution decreases The approximate number of bits for each Filter Frequency and Ran
