Solenoid/Lamp output specifications
Output type Source output （N channel MOSFET）
Rated output voltage Power supply voltage
Minimum output voltage Power supply voltage - 2.0V
Number of outputs 2 （Y17, Y20）
point 500mA maximum
Maximum output current
total 500mA maximum

Note1. For protection of output circuits, protection devices such as diodes should be connected
to output circuits with inductive loads.
Note2. For cables longer than 30m between SafetyOne and connected devices, use grounded
shielded cables to assure electromagnetic compatibility.

The specifications of the Solenoid/Lamp outputs changes depending on the Logic selected.
See further information in “Chapter 5 Logic”. But the basic specifications are the same.
Warning
Do not use solenoid/lamp outputs for safety related purposes. This may cause a loss of safety
functions in case of failure of the SafetyOne or peripherals.
