At least the wiring diagrams for this module and dataforth seem okay.</div>

While most are reporting an undervoltage condition, some are reporting an overvoltage. Seems like could be a ground issue; maybe the ribbon cable between the dataforth backplane and breakout is somehow flipped?</div>

The CLEO magnet and service neck temperature sensors are not connected to the I/O rack yet but the wiring within the rack is completed.</div>

Therefore if no signal is going to the Dataforth signal conditioners then their output should be near 0 Volts output going to the 1756-IF16 modules. The PLC should be reading a signal near 0 Volts for these temperature sensors but for the most part the PLC
is reporting input errors (input is underrange < -10.25V) .</div>
