G5 voltage or current input modules are actually frequency converters. The input to these modules is a signal from a sensor. The output from these modules is a square wave whose frequency varies linearly from 14.4 to 72 kHz and is proportional to the input signal. The controller must be able to measure this frequency and convert it back to a signal level.
The output (voltage or current level) of these modules varies proportionally to the 12-bit serial data string sent to them by a control circuit. The data string is typically 213.2 μSec long. Once a data string is received, the output is set and remains constant until another data string is sent. Therefore, the output level of the module could be changed almost 4700 times a second. For more information on programming Grayhill analog output modules, request a copy of Bulletin No. 581.
