Wiring of Single-beam Single Beam Safety Light Barriers

The activation input of the single beam safety light barrier can be directly connected to
terminal 1 on the TMC 66. The switching output of the receiver can be directly connected to
terminal 2. The GND potential present on terminal 12 serves as reference potential for both
signals. The supply of the single beam safety light barriers comes directly from the 24V
power supply unit.
