Series connection or parallel connection

2- and 3-wire sensors with binary output can be used in series or parallel connection, similar to mechanical
contacts. The type-typical voltage drop and the residual voltage U
ance with the number of sensors for series connection, must be noted. In the case of parallel connection
of sensors with thyristor output, the first switched output takes over the total load current.
