Safety relay QSRN

for light curtainDIN rail

Safety relay module meets EN/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. 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.
