L28S-3D2431, L28E-3P2431 | L28 SINGLE-BEAM PHOTOELECTRIC SAFETY SWITCHES Electrical data Sender Receiver Protection class II (EN 50178) Power consumption ≤ 35 mA ≤ 25 mA Test input voltage > 15 V or not connected (Sender on) 1) < 5 V (Sender off) 1) Test duration ≤ 2.6 ms 2) Switching outputs PNP, Q and Q not 3) Switching current ≤ 100 mA 1) The test input has a pull-up resistor to activate the sender (sender on) even when not connected. Therefore, an active-switched LOW signal is required to activate the cyclic test with test gap (sender off). 2) Signal propagation time for resistive load, for test signal application (sender) and output signal reaction (receiver). 3) Short-circuit protected.

Function The sensors switch when the light beam is clear. When sensor 1 and sensor 2 switch, the input condition for input A is met. If sen- sor 3 has switched, the input condition for input B is met. If a light beam is interrupted, the related input condition (input A or input B) shuts down the UE410-8DI. Possible faults A UE410-8DI has two test pulse generators. This means that short-circuits between odd (X1) and evenly (X2) numbered outputs will In this case, short-circuits between X1 and X4 and X1 and X6 are detected, but short-circuits between X4 and X6 are not detected. Comments Take note of the operating instructions for the integrated devices. The safety-related parameters (safety integrity level and response time) are dependent on the types used.
