Module
AI 4x15Bit [EEx ib]
You cannot use the module in redundant operation for applications in hazardous areas.
It is not suitable for indirect current measurement.
Use in direct current measurement
Suitable Zener diode 6.2 V, for example BZX85C6v2
•
Load capability of 4-wire transmitters: RB > 325 ohms
•
determined for worst case: 1 input + 1 Zener diode at an S7 overload value of 24 mA to RB = (RE * I
Input voltage for 2-wire transmitters: Ue-2Dr < 8 V
•
calculated for worst case: 1 input + 1 Zener diode at an S7 overload value of 24 mA to Ue-2Dr = RE * I
Note: You can only connect 2-wire transmitters with a 24 V external supply or 4-wire transmitters. The internal power sup-
ply for transmitters cannot be used in the circuit because it outputs only 13 V, which means in the worst case it would sup-
ply only 5 V to the transmitter.

Using digital input modules as redundant I/O
The following parameters were set to configure digital input modules for redundant
operation:
● Discrepancy time (maximum permitted time in which the redundant input signals may
differ). The specified discrepancy time must be a multiple of the update time of the
