Standstill Monitor SAFEONE DN3PS2
Our SAFEONE DN3PS2 is suitable for the safe monitoring of standstill in systems and machines, and all without a measuring system/encoder. Neither proximity switches nor incremental encoders are needed to measure the operational status.
Safe Standstill monitoring easy as pie.
SAFEONE DN3PS2 Standstill Monitor
The standstill monitors from our SAFEONE Standalone Series do not require a measuring system, which makes them truly unique on the market. They safely monitor 1- to 3-phase motors up to 690V AC with Performance Level e according to DIN ISO 13849-1. The DN3PS2 standstill monitor measures the electromagnetic force (EMF) when the motor runs down. The potential-free output contacts switch when the switching threshold, which can be parameterised on the device, is undercut.

Block diagram (terminal assignment 33PS02, 33PS03, 33PS05)
Two different function types are possible with the variants 33PS02, 33PS03, 33PS05.
The function type is selected via inputs I11 and I21.
|Function 1||Function 2|
|I11 and I21 not connected||I11 and I21 connected|
|Standstill monitoring is constantly active.||Standstill monitoring is not active.|
|Close the enabling contacts when the
drive is at a standstill.
|Enable contacts are closed (with 33PS05 only the enable contact 13/14 remains closed.
The enable contact 23/24 switches off on movement).
|The error detection "wire breakage
and "single-channel" is inactive. (not with 33PS05)

Can be used on all three-phase and single-phase motors up to Performance Level e, regardless of supplier and system.
Fits into every cabinet
With an overall width of only 22,5 mm/0.9 in
Tailored to your needs
SAFEONE DN3PS2 can be configured exactly for your needs:
Adjustable switching threshold 50-500 mV
Various adjustable delay times
Dependent on the model, via USB interface on the PC or directly via SET key. In the case of our rotational direction monitor, no parameterization is necessary at all.
Plug & Play
Easy to put into action without a great deal of prior knowledge. Integration into the circuit diagram is also very simple.
