Features
- The binary input has eight independent inputs in the voltage
range of 12 to 48 V that are connected to the electrical signals.
- Evaluation of direct current voltage signals (DC) or alternating
current voltage signals (AC).
- The binary input has a separate 24 V DC auxiliary voltage (SELV)
available for connecting zero-voltage contacts.
- Status message in case of error with the auxiliary voltage on the
bus can be removed.
- Possibility to connect meters with S0 interface (e.g. energy, gas,
water meter).
