B&R X67DS838B.L12
2 IO-Link channels (port class B) 6 IO-Link channels (port class A) Port class A: Additional digital input per IO-Link connection Each IO-Link channel configurable as a digital input or output (SIO mode) 24 VDC and GND for sensor/actuator power supply Port class B: Additional 24 VDC and GND for sensor/actuator power supply NetTime timestamps: IO-Link data The module is an IO-Link master that allows intelligent sensors and actuators to be connected per the IO-Link standard. The module can operate up to 8 IO-Link devices. All IO-Link channels can also be operated in SIO mode and thus used as digital inputs or outputs. The module is also equipped with 6 additional digital inputs that can be used independently of the configuration of the IO-Link channels. Connectors 7 and 8 are designed as class B IO-Link ports and have an additional galvanically isolated supply voltage.
