SRB-2A1B Wiring Diagram for Safety Light Curtain Automatic Reset (Internal Part)
Automatic Reset Wiring Diagram
Note:
1) OSSD1, OSSD2: OSSD signals are the signals output by the receiver when the safety light curtain operating mode is PNP or NPN.
2) After OSSD1 and OSSD2 are connected to S12 and S22 respectively, the DIP switch controls the selected mode (PNP/NPN) of the safety relay module to be the same as the OSSD signal type (PNP/NPN) of the safety light curtain output.
3) Automatic reset: Connecting SRC and SR with a wire enables the automatic reset function of the safety relay module.

Manual Reset Wiring Diagram
Note:
1) OSSD1, OSSD2: The relevant introduction and wiring method of OSSD(s) are consistent with those described in the automatic reset wiring.
2) Manual reset: Connecting both ends of the switch to SR and SRC enables manual control of the reset of the safety relay module.
MUT Wiring Diagram for Shielding Safety Light Curtain Signals
Shielding Light Curtain Signal Wiring
Note:
When the safety relay module is normally powered, connecting MUT_H to the 24V power supply and MUT_L to 0V puts the safety relay module in the shielding state. In this state, the safety light curtain signal cannot affect the safety relay module, and CH1, CH2, and the POWER light will remain on.
