Function Real time monitoring of motor winding induced residual voltage (back electromotive force) through two single ended or differential inputs When the terminal voltage remains below the set threshold of 200mV (adjustable to 4V), it is determined that "zero speed" is established, the internal redundant safety contacts are closed, and the protective door is allowed to be opened or the next step of the process is allowed If the voltage exceeds the threshold or if there is a fault in the detection circuit, immediately disconnect the safety output and keep it locked until the speed falls below the threshold again and the reset circuit is activated Electrical specifications Power supply: 24 VDC ± 20% Safe output: 2 normally open passive contacts, 2 A/250 V AC (AC-15) Auxiliary output: 1 normally closed passive contact (status) Input impedance: ≈ 1 M Ω, can accept sine and PWM residual voltage Response time: ≤ 100 ms (including contact action) Threshold adjustment: Panel knob 200 mV -4 V continuously adjustable, factory default 200 mV security level ISO 13849-1 Cat. 3 / PL e，IEC 62061 SIL CL 3，IEC 61508 SIL 3 Meets EN 60204-1 "Zero Speed Verification" and EN ISO 14118 energy isolation requirements Typical Applications Conveyor lines, centrifuges, saw blades/grinding heads driven by frequency converters: After executing STO/SS1, verify with MSR55P that they are truly stationary before opening the door Servo press and rotary table: replace external encoders or proximity switches, reduce wiring, and improve SIL level Connected in series with interlocking switches such as TLS-GD2 and SensaGuard, forming a complete chain of "safe shutdown → zero speed verification → door unlocking"“
