5.4 Power supply
A marked and easily accessible current limiting switch has to be arranged in the vicinity of
the device for turning off the power supply. Fusing should be 10 Amps or less and must be
rated for the available voltage and fault current.
5.5 Relays
When the device is switched off the relay contacts are de-energized, but dangerous
voltages may be present.
Relays are available for device versions with
a corresponding I/O extension only.
5.6 Digital inputs
The device provides a standard passive digital input / output. In addition, depending on the device version,
a 4-channel passive or active digital input module may be available.
Usage of the standard digital input
► Status input
► Meter tariff switching
Usage of the inputs of the optional input modules
► Counting input for pulses of meters for any kind of energy (pulse width 70…250ms)
► Operating feedback of loads for operating time counters
► Trigger and release signal for monitoring functions
Passive inputs (external power supply with 12 / 24 VDC required)
The power supply shall not exceed 30V DC!
