IMPORTANT: This application requires 24VDC +2 % to be present b24 and COM as is typically the
case when the AC is used to power the 7400. Operating the 7400 off of battery backup could provide voltage
values significantly different than 24VDC.
To use this application, the full scale range is set to 0 – 100%. The reading will be 0 with no alarm condition and
approximately 100% of scale when the field contacts operate. Connect resistors and relay as in the figure.
