Safety Monitor DS236

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

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).
