In certain applications, the touchMATRIX® devices DX350 or IX350 can be used as a substitute.
Type ZA634 is a two-channel universal preselection counter for various counting tasks, eg for directional, differential, total or piece counting, or the detection of lengths or positions in various fields of application in machine and plant construction. Two incremental rotary encoders or measuring systems can be connected in HTL or RS422 / TTL format. The device is designed for the switching stage installation and has 4 fast transistor outputs as well as four additional output relays.
The variant ZD634 is equipped with an 8-decade display, as well as 4 front panels, presets and a scalable analogue output (for operation with voltage or current).
