The WEJ-168 package is a modernized version of the WEJ-068 package and is intended for testing WEJ-061 packages. Twice a day, the program switches on the relays for 20 ms giving all inputs of the WEJ-061 packet voltage +220V, then 0V and reads the input states. Erroneous states are signaled to the center.

The WYJ-074 package is the object-oriented control interface. Allows remote activation/blocking of all packet relays simultaneously. It has 8 outputs with the following parameters: maximum conductivity 220V/2A DC, maximum switch-off current 220V/0,2A, each output is represented by two series-connected normally closed contacts and additionally the main relay contacts - high-current ones.

The ZWS-021 packet controls the correctness of the output matrix switching via analog path, gives 24V DC voltage to the object relays acting on the WYJ packages. The connection of ZWS-021 packets with the PWY-201 and PEW-401 packets takes place through the contacts of the ADP-002 and ADP-006 adapters.
