Short description:
The threshold value switch for analog signals monitors analog standard signals
and reports signals exceeding a preset threshold. It is equipped with an analog
input and a changeover relay output. The device features a 24VDC nominal
voltage supply. In addition, the device has a digital output (DO) to indicate
other conditions, such as a range overflow or underflow. The threshold value
switch can be configured via DIP switches and teach-in function via push-slider
switch. Configuration via FDT/DTM software is also possible.
