  • QSRN relay module meets/ISO 13849-1 Cat.4 safety requirements, suitable for high-security requirements of industrial site monitoring for various signal, including emergency stop-signal, the safety door switch signal, safety grating signal, the safety signal and hands button signal.

    ● The relay contacts are force-guided and the monitoring is more efficient and safer.

    ● QSRN has small external dimensions, the plug terminal connection, convenient installation.

    ● QSRN has 3 normally open, one normally closed of four groups of control output signal, strong control ability.

     

    QSRN- two transistor signal control

    ● Monitoring of two transistors, photoelectric switch, safety grating.

    ● With the external circuit, also can realize monitoring the normally closed switch signal of two.

    ● All circuit self-checking, when two signals do not agree to lock.

    ● Has more extensive adaptability to the grating signal residual pressure, still can work stably residual voltage greater than 10V.

    ● The ability to detect the NPN and PNP signals, a strong ability to adapt.

    ● Automatic, manual reset adjustable. Manual reset mode, the reset button is detected, forced a single reset, reset button must be disconnected before they can be reset the next.


    QSRD-two normally closed switch monitoring

    ● Monitoring of two normally closed switch signal- the emergency stop button, the safety door switch etc.

    ● Monitor the short circuit between two signals,

    ● To monitor any single switch circuit, circuit breaker, locking switch when it is not consistent.

    ● Automatic, manual reset adjustable. Manual reset mode, the reset button is detected, forced a single reset, reset button must be disconnected before they can be reset the next.

     

    QSRP- hands button control

    ● Monitoring hands button signal

    ● Button signal consistency detection, when the hand's button trigger time is larger than 0.5s, regarded as an invalid trigger.

    ● Independent double loop, all circuit self-checking, when two signals do not agree to lock.  


    FAQ

    1. Q: How many sets of output are there in the conventional safety relays?

    A: There are 3 normally open and 1 group normally closed, totally 4 sets of control output signals.


    2. Q: Can the conventional safety relays set the self inspection function?

    A: Yes, full loop self test. Lock when two signals are inconsistent.


    3. Q: Can the conventional safety relays be reset manually?

    A: Automatic and manual reset can be adjusted.Under manual reset mode, reset button can be detected. Forced on single reset, the reset button must be disconnected after the next reset operation.


    4. Q: Which safety levels can the conventional safety relays meet?

    A: Level 4


    5. Q: What is the voltage of the conventional safety relays?

    A: The voltage of the safety relay is DC24V + 10%.
