optris CS series - Open Collector Output

The sensor is offering two ways of digital communication:
• bidirectional communication (sending and receiving data)
• unidirectional communication (burst mode – the sensor is sending data only)

3.2.2 Open collector output
In case of long lines there is a drop voltage at the ground wire and the mV-output is
distorted. Because of that the brown wire can be used as ground supply and the t/c-
wire (type K) as measuring ground.
