Note! Terminals 3, 6 and 8 are at the same potential.
Note! DI4 and DI5 are galvanically isolated from DI1-DI3. To utilise DI4 and DI5 a jumper wire must
be connected. See section L for details.
Note! If control panel is available, also other macros can be selected. The digital input depends on
the macro selected.
Analogue input configuration
The analogue input signal is selected with jumper J1: AI open = voltage input (U) and AI connected
= current input (I).
Examples on selecting the analogue input signal
1. AI1 = U 0 - 10 V
AI2 = I 0(4) - 20 mA
2. AI1 = U 0 - 10 V
AI2 = U 0 - 10 V
3. AI1 = I 0(4) - 20 mA
AI2 = I 0(4) - 20 mA
