KM50x8 is intended:

  • for switching input and output lines in any combination;
  • for operation in measuring systems based on the VXIbus trunk.

The module implements the structure of a matrix switch of the form: 50x8 (50 inputs - 8 outputs).

The module performs the function of switching input and output lines in any combination.

The module provides control of the state of the switch at the level of the relay control register (closed / open).

The module provides registration of the number of responses of each relay with saving the results in non-volatile memory. The maximum recorded number of trips is equal to the relay resource without load.

Before resetting the counter (for 256 operations before the end of the relay resource), the module issues an interrupt request with the sign "End of relay resource", while the module provides the ability to receive information: relay number, balance by the number of operations.

The module provides the ability to programmatically read the number of trips for each relay.

The module provides the ability to open the contacts of all relays by one command from the PC.

Switching voltage from 1 mV to 150 V Switched current from 1 μA to 100 mA
Switching power no more than 10 W Closing / opening time of contacts no more than 0.5 / 0.5 ms
The noise voltage level induced on any channel loaded on an equivalent load of 50 Ohms should not exceed the following values:
  • -65 dB for a frequency of 100 kHz;
  • -50 dB for a frequency of 1 MHz;
  • -35 dB for a frequency of 10 MHz;
  • 10 MHz bandwidth.
The module provides verification of the main technical characteristics in the "Self-control" mode
The module provides the possibility of functional verification using an external cable by means of the module itself in the "OK disabled" mode
