Suitable for high-security requirements of industrial site monitoring for various signal.
Monitor the short circuit between two signals.

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.
