OUTPUT STATUS
The VISION features two static PNP outputs on the Receiver, the status of which depends
on the condition of the protected area.
The maximum load allowed is 500mA at 24VDC, which corresponds to a resistive load of
48
Ω
. Maxim load capacity corresponds to 2
µ
F. The meaning of the status of outputs is
defined in the table below. Any short circuit between outputs or between outputs and 24VDC
or 0VDC power supplies is detected by the barrier.

In the protected area clear condition, the Receiver supplies a voltage of 24 VDC on
both outputs. The required load must therefore be connected between the output
terminals and the 0DVC (Figure 23).
