Transient disturbance recorder for 16 analog 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 
transformer terminals. Maximum 16 analog inputs and 16 logic signal inputs are available. 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

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
