X4 This plug provides pins for 4 digital customer inputs and 2 analogue
customer inputs.
Table 7: Digital inputs (galvanically isolated)
Pin Description
3 R1: digital input 1
4 R2: digital input 2
5 R3: digital input 3
6 R4: digital input 4
7 0 V
These signals are freely available inputs, which the microcontroller transmits
into the process representation input (OPTIONS part 1, bits 4-7). The inputs
are galvanically isolated and internally connected to 0 V via pull-down resis-
tors. In an unconnected state a logical zero is transmitted. To set an input to
logical one, + 24 V DC must be applied.
Table 8: Analogue inputs
Pin Description
2 AN1: Analogue signal (0 – 20 mA)
13 GND (Systemground)
25 AN2: Analogue signal (0 – 20 mA)
28 GND (Systemground)
Via these inputs external 0/4 – 20mA sensors for transmitting the measured
values through the Profibus can be connected. .
Proposed wiring diagrams (appendix C of the operation
.
instructions) for these signals must be observed.
The bounce time of the connected switches should not be
.
more than 1 ms.
The inputs AN1 and AN2 do not have galvanic isolation via
opto-isolator.
The measuring range of the analogue inputs can be set (see Operation
instructions Profibus DP,
X2 On this plug the bus signals and the galvanically isolated voltage supply for
the bus termination, as well as the bus termination resistors on the Profibus
DP board, are connected.
