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.
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) |

Your advantages summarised
Cost-efficient
No external measurement systems equals less components, lower costs as well as faster Certification and Validation.
Be independent
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
Easy Configuration
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.
