DS236: Certified Safety Monitor with Multifunctional Inputs for HTL-, RS422- and SinCos-Sensors, without Signal Splitter

The DS236 is discontinued as of 31.12.2025. We recommend the DS230 as an alternative. More details about the DS230 ...

Like the DS230, the DS236 is suitable for connecting incremental sensors with RS422 output (differential signals A, / A, B, / B), single-track HTL encoders and sine-cosine encoders. The DS236 is equipped with a relay, 4 transistor outputs and one analog output, but it does not have a signal distributor (unlike the DS230).
