Introduction
The PET-7016 is a strain gauge module with 2 analog input channels, 1 excitation voltage output channel, 2 digital input channels, and 2 digital output channels module. It provides various programmable analog inputs (+/-1 mV, +/-50 mV, +/-100 mV, +/-500 mV, +/-1 V, and +/-2.5 V) and supports full-bridge, half-bridge, and quarter-bridge. The range for each analog input is allowed to be configured individually. The excitation voltage output can be in the range of 0 ~ 10 V with a 60 mA driving efficiency. Digital outputs can also be set as alarm outputs. The PET-7016 can also provide long-distance strain gauge measurement that compensates for the loss of voltage resulting from long-distance measurements.
