Transient disturbance recorder for 16 analogue channels, MEDREC16

The transient disturbance recorder MEDREC16 is used for recording the current and voltage waveforms,
as well as the status data of internal IEC 61131-3 based logic signals and digital inputs connected to the
relay terminals. The maximum number of analogue inputs and logic signals is 16. One fundamental cycle
contains 40 samples.

The recording can be triggered by any (or several) of the alternatives listed below:
- triggering on the rising or falling edge of any (or several) of the digital inputs
- triggering on overcurrent, overvoltage or undervoltage
- manual triggering via the menu or with the push-button F on the front panel (if configured)
- triggering via serial communication or a parameter
- periodic triggering
The recording length depends on the number of recordings and inputs used. For example, the following
combination of recording length, number of recordings and number of inputs is available at 50 Hz:
