îš„Switch S1 and Jumper CN15 - Optional Terminal Board
An optional terminal board which supports switching the signal type of the analog outputs FM and AM
between voltage and current is available.The switch over can be performed using jumper CN15. The switch
S1 has the same function like on the standard terminal board. See Fig 2.20 for details.
Fig 2.20 Optional terminal board - Switch S1 and jumper CN15 function
The settings of switch S1 and jumper CN15 are described in the following table.
îš„ Sinking/Sourcing Mode
The input terminal logic can be switched between sinking mode (0-V common, NPN) and sourcing mode
(+24V common, PNP) by using the terminals SN, SC, and SP. An external power supply is also supported,
providing more freedom in signal input methods.
