QSRN Series Safety Relay Module

The QSRN safety relay module meets the safety requirements of EN/IS013849-1Cat.4 and is suitable for monitoring various signals in industrial sites with high safety requirements - including emergency stop signals, safety door switch signals, safety light barrier signals, and safety light curtain signals. Outside the two-hand button signal.

  • Forced guidance of the relay contacts makes monitoring more efficient and safer.
  • QSRN has a smaller external size and is pluggable for easy installation.
  • QSRN has 3 normally open, 1 normally closed, a total of 4 sets of control output signals, and the control ability is stronger.

QSRN - Two-Way Transistor Signal Monitoring

  • Monitor two transistor signals - power off switch, safety light barrier, etc.
  • With the peripheral circuit, the monitoring of the two normally closed switch signals can also be realized.
  • Full loop self-test, lock when the two signals are inconsistent.
  • It has a wider applicability to the residual voltage of the grating signal, and it can work stably when the residual voltage is greater than 10V.
  • It can monitor NPN signal and PNP signal, and has stronger adaptability.
  • Automatic, manual reset is adjustable. In the manual reset mode, the reset button can be detected, a single reset is forced, and the next reset operation can be performed after the reset button is turned off.

QSRN - Two-Way Normally Closed Switch Monitoring

  • Monitor two normally closed switch signals - emergency stop button, safety door switch, etc.
  • Monitor the short circuit between the two signals.
  • Short circuit to any single switch, open circuit monitoring, lock when the switch is inconsistent.
  • Automatic, manual reset is adjustable. In the manual reset mode, the reset button can be detected, a single reset is forced, and the reset button must be turned off before the next reset operation.

QSRP- Two-Hand Button Monitoring

  • Monitor two-hand button signal
  • The button signal is detected once, and when the two-hand button triggers the time difference greater than 0.5S, w it is regarded as an invalid trigger.
  • Independent dual-loop operation, full-loop self-test, lock when the two signals are inconsistent.
