Safety Outputs
The safety outputs have a redundant circuit design, and an error occurs if the inputs are mismatched for two or more seconds.
There are three channels for safety outputs, each with independent output terminals. To use the output terminals, external 24 V and GND power must be supplied.
When connecting the wires, check the safety I/O connector pin assignments in the signal arrangement.
Safety Output Specifications
Interface specifications
To use the safety outputs, a SELV-certified external power supply is required.
The connection wires should be AWG26 and should not exceed 20 meters in length.
Available functions
The following functions are available when configured in "Safety Function Manager." For details on the settings, refer to the following manual.
"Robot Controller Safety Function Manual"
- Enable ON/OFF
- Emergency ON/OFF
- STO State ON/OFF
- SLS State ON/OFF
- SLP State ON/OFF
Safety output electrical specifications
Rated output voltage: +24 V ±10%
Maximum output current: Max. 100 mA per output
On-resistance: Typ. 5.5 Ω
The output circuit can only output Source. Do not connect in reverse.
Connect the power supply to 24 V (A2) and GND (A1), and use the output of each terminal as Source output. Refer to the connection examples.
