AUX (Auxiliary) Output
The AUX (Auxiliary) output is a NON-SAFETY-RELATED function.
This output just informs an external device (non safety-related device) of the operations of the SL-V and
operates in synchronization with OSSD operation. It can only be connected to a PLC or similar non-safety
devices.
The AUX output is not allowed to be used as a safety output for safety-related control
systems. This output does not constitute a part of the safety-related control system. Usage
of this function as a safety output may result in significant harm to the machine operators
including injury or death.

Wiring
Output rating : 26.4 V DC or less, 50 mA or less
Regardless of if you are using an NPN or a PNP cable, the SL-V AUX output can be connected to PNP
and NPN devices. Refer to the time charts mentioned in this manual because the AUX output logic is dif-
ferent depending on the connected device.
