3.1 Terminal and block diagram
The figure below shows an example of the pin assignment of signal inputs with 2-wire and
3-wire connection and of signal outputs in the configuration modes for digital inputs and
outputs.
① Configured as inputs: 2-wire connection 1L+ Supply voltage 1L+ (non-switched)
② Configured as outputs 1M Ground 1M (non-switched)
③ Configured as input: 3-wire connection 2L+ Load voltage 2L+ (switched)
④ Configured as output 2M Ground 2M (switched)
⑤ Configured as input: 2-wire connection 2U
