Motrona DS230 Safety Speed Monitor with Multifunctional Inputs and Signal Splitter

The task of a speed monitor is, as the name says, the monitoring of overspeed, underspeed, direction of rotation or standstill. The speed monitors from moTrona are used when there are high safety criteria for the safety and reliability of a system. In particular when the highest protection requirements for man and machine are needed, the safety relays of the DS series, with the double certificate according to DIN 61508 and ISO 13849, offer a high level of safety.

The DS230 is suitable for connecting incremental sensors with RS422 output (differential signals A, / A, B, / B), one-track HTL encoders and sine-cosine encoders. It is equipped with a relay, 4 transistor outputs, one analog output and one signal distributor.

The DS236 is an alternative version without a signal splitter.
