Remote Automation Solutions MVS205 Case Isolation

The MVS205 Case Isolation is a device that provides electrical isolation between the case of the MVS205 transmitter and the ground. This can be useful in applications where it is necessary to prevent electrical noise from the case of the transmitter from interfering with the signal being transmitted.

The MVS205 Case Isolation is easy to install. Simply remove the cover from the conduit end of the MVS205 transmitter, remove the jumper attached between terminals CS and DR, connect a ground wire (size 12 to 14 AWG) to terminal DR, and connect the other end of the ground wire to an earth ground.
