Overload Output
The DRI possesses an overload output feature (DFS-CTRLCABLE) to protect the load cell or torque sensor. When the load exceeds
150% of its capacity, an open collector transistor turns ON (there are two OC NPN transistors, one for tension and one for compression).
The output of these transistors can be used as an alarm or to stop a process, thus protecting the remote sensor or the sample under test. See
“Display and Keypad” section for the location of the overload output port.
NOTE : This output is always active, therefore no parameter selection is necessary.
TENSION
COMPRESSION
COM
Both transistors can handle up to 28VDC, 5 mA.
