Functional safety related parameters
MTTFd620 a
Mission Time (TM)20 a
Diagnostic Coverage (DC)90 %
Indicators/operating means
Operation indicatorLED green
Function indicatorLED yellow:
1. LED lit constantly: signal > 2 x switching point (function reserve)
2. LED flashes: signal between 1 x switching point and 2 x switching point
3. LED off: signal < switching point
Control elementssensitivity adjustment (Adjustment to < 25% of the effective operating range) , Light-on/dark-on changeover switch
Electrical specifications
Operating voltage10 ... 30 V DC
Ripple10 %
No-load supply currentEmitter: ≤ 50 mA
Receiver: ≤ 35 mA
Input
Test inputemitter deactivation at +UB (Imax. < 3 mA at 30 V DC)
Output
Stability alarm output1 PNP transistor, short-circuit protected, protected from reverse polarity, open collector, Umax = 30 V DC, Imax = 0.2 A
The output becomes inactive if the signal level has fallen below the function reserve for approx. 10 s (yellow and red LEDs flash).
If the light beam is interrupted four times during this period, the output immediately becomes inactive.
Switching typelight/dark on, switchable
Signal output2 PNP, complementary, short-circuit protected, reverse polarity protected , open collectors
Switching voltagemax. 30 V DC
Switching currentmax. 200 mA
Switching frequency1000 Hz
Response time0.5 ms
Timer functionON delay (GAN), OFF delay (GAB), one shot (IAB), ON delay-one shot (GAN-IAB), ON delay-OFF delay (GAN-GAB), programmable
adjustment interval 0.02 s ... 1 s
