Currently the plasma turret has a "plasma-sticker" effect that poisons you and slows you down for 30 seconds, which is excessive imo.
Because of this duration, getting hit by your own plasma turret is always a death sentence, as even if you have high enough armor to survive the hit you will lose your health gradually over time and end up dying anyway. This is also a very confusing effect for the player as no weapon in the game functions like this so you end up wondering why you're losing health 15 sec after getting hit.
This effect barely affects biters (they are going to die way before 30 seconds anyway) so I don't see the reason for its existence. On top of this, I think plasma turrets are still OP but this is an other topic :)
The duration can be adjusted with:
-- nerf duration
data.raw["sticker"]["plasma-sticker"].duration_in_ticks=1*60
