The SA644 was discontinued on 30.09.2023.
In certain applications, the touchMATRIX® devices DX350 or IX350 can be used as a substitute.
The display unit SA644 corresponds to the device type SA640 in all functions as well as the design. It is used as a universally programmable frequency and/or difference display with 2 incremental encoder inputs, which enables to recording of two speeds and lead times. Due to this speed ratios or differences of two different channels can be evaluated and visualized.
The SA644 version additionally has 4 front-side thumbwheel switches for fast and direct presetting of limit values for the switching function of the transistor or relay outputs.
